My question is, I received a pre-approval for the Bank of America platinum card in the mail. Now I know that I will not receive the platinum, but maybe the gold or classic. I went to the website indicated and filled out the form, and it came back saying that I was approved for a gold account w/ 2500 credit limit and that my card would be mailed to me in five days. Can they go back on this offer? Can they end up sending me a classic card w/ 200 credit limit? Any advice would be greatly appreciated!
