[Resolved]  ABN AMRO / Personal Loan — Claim of Pending Amount even after Full & final Settlement

I had availed a Personal Loan from ABN Amro during 2004, had some issues with last few installments. Eventually during Oct' 08, their Recovery Team came up with a Full & Final Settlement for 10000/-, which i agreed instantly & settled by DD, which was also mentioned in the F& F letter given to me by the Executive. For the last 15 days i have been receiving calls from Delhi no. stating that an amount of 25, 000/- is pending. When i mentioned that i am in receipt of F& F letter from the bank, the guy informs me that the letter is only for Prinicipal amount & not for the interest portion. When i tell him i cant help him, he tells me that he would send the collection guy. When you get a bit irate on the line to him, he threatens saying that he would publish my name in CIBIL, which would tarnish my image. Funny that there is no Site, where we as citizens who have sincerely cleared our outstandings, can Blacklist these banks. Someone can tell me how to handle this situtation.
