Is your organisation (Reliance) an exempted organisation who is allowed to keep their own PF accounts? If not, then you have to apply for withdrawal of PF through your member portal. The employer has nothing to with it other than marking you exit from the EPF.
How long did you remain in service? Did you service 10 years? Did you cross the age of retirement, ie, 58 years? If yes, you can apply for pension through your member portal. Before that please ensure that you have done the e-nomination which is again an activity that you, the member, have to do by yourself.
Please confirm
