Product: Checking or savings account

I received emails and physical mails regarding promotion for opening an accelerated savings account. Terms for the promotion will be listed at the bottom of my complaints. 

I opened the account In mid XXXX through the link sent to my email. I also called right after I opened the account to ensure I am enrolled and qualified for the promotion. I have kept my balances in the account for over XXXX $ USD to meet the qualifying deposit. When I didn't receive the bonus in XXXX, I called Citibank. The customer service ensured me that I've met all the requirement and I should receive the bonus by XX/XX/XXXX. However, when I called again in XXXX, they told me they couldn't find a promotion attached to my account, and refused to honor the promotion. I've done all the right thing to make sure I am enrolled in the promotion by applying through the link sent to my email and called in to be asked for enrolling in the promotion. I've tried to dispute it with Citibank, but no one can give me a specific reason except they couldn't find the promotion attached to my account, and that my account is a basic package that did not qualify for it. I can not talk directly with the " backend '' people who made the decision for the dispute and so far no one can tell me why I was not enrolled for the promotion. 

Terms for the promotion are listed below. In order to enroll, one can either apply through the link provided or call the representative to ask to be enrolled. I did both to double secure my eligibility, and it was clearly some mistake on the backend of Citibank that led to me being not qualified for the promotion. I am sure all the phone calls are recorded and I request Citibank to do their investigation and honor their promotion, or it would be a clear fraud/deception.
