Since there is so much of uncertainty about the recovery agency, we advice that you should not make any further payments till you get written communication. The Supreme Court has in few judgments frowned at the high-handed tactics of such debt recovery agents and has made it clear that such agency can not use threats or muscle power to recover the money. We would suggest that you write a very firm letter stating that unless and until you do not see the documentation that allows them to recover the loan from you, you will not make any payments. You are advised not to make any cash payments. You can also tell them that if they continue harassing you, you will approach the police. If it is a genuine claim they will revert to you with the documents and if its not genuine they will back off when you tell them that you will approach the police for the harassment meted to you.
In such cases, the entire paper trail is important. Once you have closed the account or paid the entire sum of loan, the bank shall issue a no dues form. But more so, we need to be sure that the loan has actually been forwarded to Fin Cruise for which you will have to do some research and paper work. Further, in case there is any property that has been mortgaged, the bank will issue discharge letter and hand over the documents as well.
