Need expert opinion on disparity with offer of employment

You have case in respect if cheating and non-discloser of terms of employment but in respect of dues you don't have case. Instead of police complaint, you should file private complaint before the Magistrate for effect disposal of your complaint. Meanwhile check whether this company is registered or not? It may come to your notice that some big fraud is going on. You will find details of Company from web site of Ministry of Corporate Affairs.

Thank you for the quick response. 

I will take this issue up as suggested. Thanks once again.

Did checked the Ministry of Corporate Affairs site to confirm that the company has been registered.

You have not posted which designation/Role was mentioned in offer letter issued to you?

Did you sign it towards acceptance?

Do you have the copy of job advt, job application that show the job advertised, Role ,Title? 

Sir, Please find the answers below.

Role mentioned in offer letter: QA Head

Actual role alloted in the internal system: QA Manager

The appointment letter which was signed by both parties (myself & the HR Manager) reads Product QA Head.

Job descripttion shared was initially for QA Manager. I was invited for discussions mentioning that the role might vary based on the interview performance; Initially the offer was rolled out for a QA Manager role and I declined the same. The counter-offer was made with title 'QA Head'.
