Citibank Credit Card Complaint

Citibank Credit card department,

Advertising and marketing Virginia

Hi, I applied for my credit card when the offer on the website showed specifically that I would get - - - Miles after spending $0.00. The bank later started saying that the offer is for spending $5000.00 and not $0.00. I have sent confirmation and also confirmed from several representatives and for 6 months, every month i am told it will be deposited next month but it never happens.
