4. Why is my purchase not reflected on my online transaction history?

When you present your card or credit card number to a merchant for payment, an authorization is created. Until the merchant submits the transaction to the issuer for posting, your authorization is considered pending. When the issuer receives the transaction from the merchant, it is posted to your account, subtracted from your pending authorization balance and added to your current balance. This could take up to 1 - 3 business days before your purchase is reflected in your online transaction history.

Payments made via OMISTA Online Banking or Telephone Banking before 6 pm Eastern time or at a OMISTA bank machine before 6 pm local time will be credited on the day the payments were made, but will not show on your credit card balance for 1-3 business days later.

Payments made via OMISTA Online Banking or Telephone Banking after 6pm Eastern Time or at a OMISTA bank machine after 6 pm local time will be credited next business day and not show on your credit card balance for 1-4 business days.

If there is a charge on your statement that you do not recognize (or any other error or omission), you must notify MasterCard® within 30 days after the date of the statement on which it appears. Please contact Credit Card Services with the details of the transaction (e.g. date, description of the transaction and the date of the statement).

7. What are pending authorizations?

When you present your card or credit card number to a merchant for payment, an authorization is created. Until the merchant submits the transaction to the issuer for posting, your authorization is considered pending. When the issuer receives the transaction from the merchant, it is posted to your account, subtracted from your pending authorization balance and added to your current balance.

8. What is Automatic Bill Payment?

Automatic Bill Payment is an arrangement where you can pre-authorize a merchant to automatically charge your MasterCard^® card account on a regular basis. Payments may be made monthly, weekly, quarterly, etc. — depending on what you and the merchant agree upon. The pre-authorized payment can be a fixed dollar amount, or it can fluctuate like your phone bill, depending on the terms of the agreement. And, you can stop automatic payments at any time or use this payment method indefinitely.

10. What are the benefits of Automatic Bill Payment?

Because bills are automatically charged to your MasterCard® card account, it’s much faster than writing cheques. Charges will appear on your monthly MasterCard® statement, so it’s an easy and efficient way to keep track of your expenses. And because it’s automatic, you won’t have to worry about missed payments or late fees. Plus, depending upon the MasterCard® card you elect to use, you may be able to earn rewards in MasterCard® card usage frequency programs, such as frequent flyer and point programs.

11. Which cards can I use?

You can use any MasterCard® card — as long as it has the MasterCard® logo.

12. What information will the merchant request?

Generally, the merchant will need your account number from the front of your MasterCard® card. They will also need the expiration date, the dollar amount they are authorized to automatically charge, and the specific date you wish to be charged each month. Note: Not every merchant will allow you to choose this date, but many will. Some merchants may require additional information, such as your signature.

13. Who is my card issuer?

The financial institution, OMISTA Credit Union, issued your MasterCard® card(s). If it was not OMISTA, usually, you can look at your MasterCard® card(s) to determine the issuer. If you have trouble identifying the issuer, there should be a customer service phone number listed on the card(s) as well.

14. Do I have to pay an extra fee for Automatic Bill Payments?

Most merchants do not charge a fee, but you will have to contact each of them to determine if there are any fees or restrictions associated with participating in their automatic payment program.

15. What if I pay my MasterCard® bill late?

Your automatic payment to your merchant should still be made, even if you pay your MasterCard® bill late. However, you will need to refer to your cardholder agreement with your MasterCard® card issuer to determine how your issuer will handle new charges if you are delinquent in your payments.

16. How often can I make payments, and when do bills get paid?

Each merchant has its own procedure for Automatic Bill Payment. You will need to clarify these procedures with the merchant when you initiate your Automatic Bill Payment relationship.

Just contact the merchant with whom you’ve set up the Automatic Bill Payment, and then simply follow their procedures to cancel or change the method of payment.

18. Will I receive a bill for my records after I have been charged?

Yes, most companies continue to mail a bill indicating the total amount they will charge to your MasterCard® card. However, some merchants may allow you to elect to receive an online bill — via the Internet — or no bill at all. At the time you initiate an Automatic Bill Payment relationship, you should determine how the merchant will bill you. Also, your MasterCard® card monthly statement will provide you with a convenient, thorough record of charges to your MasterCard® card account.

19. Is there a limit to the number of Automatic Bill Payments I can have on a card?

No, but you may be limited in making overall charges to your MasterCard® account if doing so would cause you to exceed your credit limit.

MasterCard® is accepted at more than 24 million locations worldwide. Even so, not every merchant offers their customers the ease and convenience of Automatic Bill Payment that’s available through MasterCard®. Because each company makes its own payment option decisions, we encourage you to request that your merchant/service provider consider offering this convenience to you.

24. Am I liable for any incorrect charges a merchant makes?

If there is an error in billing, simply contact the merchant to resolve the issue. You should also be familiar with any procedures required by your MasterCard® card issuer concerning this type of situation. This will help you to easily dispute an incorrect charge and protect yourself under applicable federal law.

25. What if my MasterCard® is new/changed or lost/stolen?

To report a lost or stolen card, call us at 1-800-LOST-111 (1-800-567-8111), or if outside of North America call us collect at 1-306-566-1276.

Upon receiving a new card, you must contact each merchant/service provider with whom you have an automatic bill payment relationship to update your information. Timely updating of your new information hopefully will preclude any interruption in your service.

26. Who is responsible if a payment arrives after its due date?

The merchant will charge your MasterCard® card at a predetermined time, which will be stated in your Automatic Bill Payment program agreement. You should schedule your payment at least five days in advance of the due date. However, to be safe, you can check with your card issuer to determine liability due to late payment.
