Employer preventing to join other workplace

Sir , i have resigned from job on 17.10.2019 by a letter dated 17.10.2019 with immediate effect. however company provided one month salary but no release letter . in fact company meanwhile prevented me from joining new workplace by issuing new employer that " due to some official liabilities the said employee cannot be released from duty . but if any misconduct has been done from my side rather than initiating disciplinary proceedings the former employer keep it watching silently without taking any action and not communicated to me the same but alleging of unauthorised absent . however tendering resignation and unauthorised absentism from duty are not same. but if the grievous charges like unauthorised absentism occured then it should must be subject to inititate disciplinary action but authority keep remain silent. i had requested sevaral times to release me from duty but authority did not pay heed to it. through a RTI letter i have asked authority that whether my resignation has been accepted? they informed me through a letter that " no such information is available" in a nutshell still now no disciplinary proceedings initiated , despite of that prevented me to join other workplace , indirectly they are approaching me to join them again. this is the fact . now i want to know that does i am entitled to get notional benefits along with pay and arrears for the whole time ? no work no pay principle will apply in this case or not? do i am eligible for reinstatement?
