Not getting Release letter - sent several emails to the ex-employer however no reply

After working for 7 months as a confirmed employee I left Sun knowledge Pvt Ltd. due to medical reasons. After system pickup HR sent me an abandonment of employment email to me, I replied that I resigned but no reply from them, this had happened back in 2021 Sep, This year in Aug I again follow up regarding my letters and FnF settlement and I am ready to pay if there is any due. No reply, now I'm in Tcs, and they are asking me for the service letter, again I sent several emails to the ex-employer however no reply. On a phone call, they asked for all the proofs again and they said they are not sure but they will check if they can provide the letter or not. I have no time, one week left to submit otherwise have to lose my job. Super nervous, please help.

Hi,

From your message I presume you haven't served proper notice period after submitting resignation right ? After submitting resignation you should visit office and discuss with HR even if you are not in a position to serve proper notice period. Looks you are communicating through emails with your ex-employer. Better contact your HR by person and discuss about your requirement, express your willingness to pay money towards shortfall in notice period. It all depends on your negotiating skills.
