Mental Humiliation at Workplace

Hi, I am facing a lot of humiliation in our office. 1. 20% dedication in salary 2. Late Night Work 3. Excess working hours 4. Mental Pressure 5. Insulting in-front of the entire team 6. Regular taunting on my abilities In March 2020 they have asked me to resign with 10 days notice as they thought i am not capable. After this they extend weak by week, without thinking about my financial and job situations. They took me back and not i have been really humiliated. This all effected my mental and physical health. I have resigned on 23rd July 2020 with 10 days notice period because of my health conditions. I have not received any revert so far. HR called me asked me to give more time so that they can find another resource. Please suggest.
