Tech Mahindra — relieving letter

Address:

Hitec City Tech Mahindra BSG, Hyderabad, Telangana

I missed out on procuring my relieving letter 5 years back and now need it. I was working out of tech m hyderabad in 2014. The exit team doesn't even have my records and neither the portal carries it. They asked for my resignation acceptance which i sent them on email and they mentioned they ll send it shortly. How? When? Is not answered at all. The exit team doesnt have a number just an automated mailbox. Pls help.
