What is this excuse of Collection agencies you are giving me ? Be Bold and DEMAND things.
1. Give a letter to the bank in writing for settlement. Give them just 15 days, on the photocopy of the letter get acknowledgment. Warn them in the letter that failing to resolve the issue, you will appeal with the Banking Ombudsman and mark a copy to RBI Ombudsman.
2. If the bank asks to pay some amount, go ahead and pay in the bank via a/c payee cheque only favoring your credit card account. But with that attach the letter as well.
3. You should know that your credit history will be damaged if you have "SETTLED" and not paid in full.
Best
