I responded to an offer to upgrade my credit card and receive XXXX for XXXX airfare. I needed to call in a registration code and charge {$3500.00} by a certain date. I did, and a month later, verified. I was told to wait another 45 days to receive airfare certificate. I never received certificate and have called numerous times, being passed from dept to dept. Apparently, there is a communication gap between Bank of America and Visa, the XXXX companies involved. XXXX have told me the other is responsible for the reward certificate. Finally, after many unhelpful clerks, XXXX XXXX in XXXX, spent XXXX minutes making XXXX way calls to dept after dept with no success. I would have charged the required amount on a trusted card that has actually rewarded me. I responded to this offer a year ago, and Bank of America has had a security breach during the year, so my credit card number was cancelled and I was issued a new number, but it 's the same account.
