I have given a notice period of 15 days to my company against the notice period of 1 month which actually company requires. But I gave the salary of remaning 15 days which were short of notice period. After 3 months , I requested my HR to issue me the relieving. They did so but by mistaka they put my wrong joining date in the releiving letter. So I asked them to send me the revised one for which they agreed. But now the case is, just before sending the new relieving letter, they told me that I have to pay RS 31000/- to them to get it as I have not served my full notice period. I said I gave 15 days notice period and other 15 days salary to them. So they say that your resignation wasnt accepted and you chose to leave the company and so they are not couting that 15 days notice period. First of all they didnt tell me all this before sending the previous (wrong date ) relieving letter. Now they are adamant of that. In the policy also, there is nothing mentioned about this sort of situation that if notice period is not accepted. Please guide me as to what should I do.
