Complaint Review: CCA Credit service Divison

I'm a college student, and i recieved a letter from CCA Credit service Divison and a credit card with a supposed value of 6500.00 (credit limit). I called and i couldn't really understand at first but it became clear when all they kept asking for is my checking account number. I looked up the web sight on the internet and i couldn't find a web site to place your orders. I called them back and i tried to get answers about the company but all they kept doing was asking for my credit card number. If you read this please don't give them your checking account number they will try by any means that they can to get it Erik Chicago, Illinois
