I had a CC with BoA that I stupidly closed due to my impending divorce proceedings a few years ago, wanting to clear my financial portfolio in going into the divorce settlement, Anyway, my dirty laundry is not the issue. Last year, after reading these forums, and realizing the stupidity of my action, I contacted BoA, and asked that they reactivate the card. They agreed. They gave me a new account number, and transferred all of my prior credit history, en toto, over to the new number, and the account was essentially reactivated.
I am not saying that this is typical of any CCC, but I can testify that it can be done.
