Dear member,
If you feel there is an inaccuracy in the computation of your terminal dues, have you brought the anomaly to the notice of the concerned authorities? If yes, how was it done? What reply have they given?
If the reply given by the company was also wrong or if no reply was given at all, what further correspondence have you done?
Hereafter, start sending hard copies of the letters you send to the office. Yes, I know you are from the IT company, and what I am recommending may seem ridiculous; however, in case you are required to approach the court in the future, you need to have tangible proof of correspondence at hand, and for this, you need to do this.
The last resort is to approach the MD of the company. Prepare the letter, take a printout, scan the copies, then send the letter by speed post. Scan the receipt of the printout also, and you may send the whole thing by email. However, the transmission of the soft copy should be in addition to the hard copies. Prepare a file to store all the hard copies chronologically.
Thanks,
Dinesh Divekar
