Unauthorise absence/ dies non and stoppage of wages

Sir, I am working in PSU (Central) organisation since from last 28 years as Supervisory category and 5 years more service. Since from last 10 years deptt. is harassed me like Manhandling,non sanction of leave,HBA loan, and degrading because I had asked Information regarding service matters through RTI. Due to this I had filed cases on Civil /criminal PC cases on college since there is no action from Organisation. on September 2016 Intersection transfer letter and relieving order was issued to me at a time to more harass me and force to report Junior officer.But I had reported concern Head of the Department as per relieving order and not reported to junior officer as in transfer order. Subsequently I had submitted representation to HR/ Unit Head to demote to lower grade position along with Relinquishment of higher position to report Junior officer. HR is denied for this and issued letter to join. Since the entire service matter is not resolved from last 10years I had lodge the complaint at PMO PG for revoke the order and inquiry/action is under process.Now 3 months is passed and HR is issued letter to me as Unauthorised absence and Dies non results withhold of payment/allowances. Please advice next step. regards
