It is clear that your matter has not been handled by Generalist; HR person.
Your matter seems to have been handled by seasoned IR persons in consultation with Legal cell/Law Firm.
Your stakes are high.
You have been involved in tricky situation.
You have signed some documents.
You want to claim that you signed under compulsions.
Since you did not join at location where you were tranferred, probably the salary was not processed, at all.
You want to agitate on issue of back wages, Forced resignation etc etc.
The onus to prove is on you.
As already Posted: The counsel that has examined all docs, facts on record can advise you the best on steps that you can take, draft your plea the best and argue the best possible for you. Your counsel might have advised you to atleast submit a police complaint under proper acknowledgment.
