Upgrade transaction wont go thru

Are you receiving an error message of any kind when attempting to process the transaction, Yiolya? If so, can you copy and paste that message for me in a post, or simply type it out word-for-word? :)

Q u o t e:
"Transaction unsuccesful. If you are sure the credit card number was entered correctly, please contact Billing and Accounting Services for further assistance"

This particular message can indicate a few things. Most commonly, a detail related to the correct is entered incorrectly—like the zip code or the verification number. In other cases, it's simply a browser issue; attempting the transaction again in a different browser often helps alleviate the issue.

You're welcome to try the transaction again with the above in mind, or you can give our Billing & Account Services department a ring. Our representatives therein will be happy to assist in any way that they are able.

Q u o t e:
That was the message I received several times even though it still charged my account 5 times.

I don't believe we've actually charged you for those unsuccessful transactions. Rather, it sounds like your financial institution has simply placed the appropriate amount of funds on hold for each requested transaction. If the transactions fail (or do not complete), these funds should be released back to you by your financial institution, in accordance with their banking policies.

Here's a bit more information:

Q u o t e:
Depending on your financial institution and the terms of your credit card, the authentication process may place a "funds held" for verification purposes. This is a temporary charge that will reverse itself automatically, generally within three to five business days. However, some financial institutions may hold the funds for up to 30 days, depending on their own policies. Please note that these charges are simply part of the verification system. Because of other circumstances beyond our control, these charges do not indicate whether a card will be accepted at the time of payment. In the event that the charges do not reverse in three to five business days (please allow for more time on holidays and weekends), please contact your bank and verify the charges in question. You may also want to inquire with your financial institution as to what their policy is on reversing "funds held" transactions.
