Citibank Credit Card Complaint

Citibank Credit card department,

Advertising and marketing Colorado

CitiCards sent me an offer in the mail for an - - credit card with a promise of - bonus miles if I signed up for the card. I applied for the card online as instructed and was approved and received the card. After meeting the minimum purchase requirements I still had n't received my bonus miles so I called and asked why. I was told that because I had had a similar card in the last 24 months that I was n't eligible for the miles. If this was the case then why did CitiBank send me the offer in the first place? When I applied online why did n't the system tell me that I was n't eligible? I would n't have taken the card without the bonus miles. This seems like a scam to me.
