Citibank Credit Card Complaint

Citibank Credit card department,

Rewards Arizona

In -/-/- I applied and was approved for a Citi AT & T Access more card, it came with a bonus offer of a free att phone ( $650.00 ) worth if you spent $2000.00 in 3 months, which I did. I did not use the offer immediately because the terms and conditions of the offer listed no expiration date. I called in on -/-/- to check if the offer was still attached to my account and the lady said that it has expired. I then rechecked all the terms to make sure. Multiple calls and chats led nowhere, no offer to redo the spending requirement ( which I am willing to do ), no offer to fix the expiration problem.
