Tata AIA Life Insurance — Resignation

Address:

Tata AIA life insurance Devalaya building 2nd floor 3A gariahat road kolkata 700019

I am an employee of TATA AIA LIFE INSURANCE for last 2 years and due to personal issues I wanted to leave the organization but whenever I submitted my resignation it got either denied or put on hold with some reasons which are absolutely not acceptable neither are true even though I pledged for a termination not bothering about the career then also company did not pay any attention to it as their soul concern is to take out the business from the employee till the time the employee is alive
Now please suggest what to do in this circumstances as in this organization I'm being victimized in the arms of my higher management
