How Can I Get a Relieving Letter from a Closed Company Like Reliance Communications?

Dear friends, Currently, I am working with Bharti Airtel Ltd as a Territory Manager. The previous company I worked for is Reliance Communications. Now, I am leaving Bharti Airtel Ltd and joining Reliance Jio. During the documentation process, I need to submit a Reliance Communications Relieving Letter. However, as that company has now closed, I am unsure where to obtain it. I have received an acceptance email from HR, but my Full and Final Settlement has not been completed. The Relieving Letter is a mandatory requirement for submission. How can I obtain it? Any assistance would be greatly appreciated.

Employee ID: 20052892

Joining Date: 06.12.2014

Relieving Date: 06.06.2016

Company Name: Reliance Communications

Ask your HR contact at your new Reliance subsidiary to deal with this problem. All the records for Reliance Communications must be housed somewhere within the Reliance conglomerate. No one here can give you the letter. Failing that, I guess you could petition Mukesh Ambani to get the problem sorted if none of the thousands of staff he employs will do it. :-)

Reliance Jio has taken on thousands of people who were previously employed by Reliance Communications when it closed. None of them received any documents or settlements as the company is bankrupt. It would be surprising if they have not already factored it in. Have you spoken to the HR in the new company and asked them about it, or are you just assuming? You received an acceptance email for what?

Reliance Communications and Ownership
John, Reliance Communications belongs to the younger brother and not to Mukesh Ambani, so he will not have the data. The company went bankrupt and simply closed without paying many vendors and employees. I doubt if anyone is left in HR now.
