Iam lost did you receive a check for 2,500. from the old credit card or the back card? I would call the bank card and find out exactly what is owed on it at present. If they accidently sent you a credit check then it will prob show as a 5,000 total on your debit (2500. for the balance transfer and 2500 cash back). I wouldn't go spending $ that isn't accounted for.
