Dear Mr. Sushil,
The poster says the company has sent him a letter - is it a legal notice or just a company correspondence asking for Rs 65,000? This is where most posters fail to give correct information, which can give rise to wrong interpretations. If it is a legal notice, then the ex-employee has to tackle the matter legally. If it is a normal letter from the company HR, he probably can choose to ignore it or reply only based on legal advice because what he writes can be used in any subsequent legal proceedings, if any.
