To launch compliant for HR

My HR and the advisor to chairman has created from me the circumstances such that I say no to my given task from management purposely and send me the termination letter as headed last warning letter with deduction from my salary Rs. 20000 and also suspended me from my current services with no such suspension l imit as I need to wait till further management discussion and they have created committee who takes such false decesion and harass the staff . There are two such can cases within my team itself as they have kept my July month salary also on hold . Pls advise me further how to go about . Also request to conect me on my cell 9833737002
