Sterling Hospital — Staff nurse

I am sukhdevi rathod. EMP no[protected]. I was a staff nurse at sterling hospital memnagar for 2 year.
I submitted my resign on 18 jan 2021.
At first they are not accepting my resignation and after long request they accept my resign.and now it been a 5 month of resign they are not providing experience certificate so i request to HR Manager bina patel. Kindly sign experience certificate and provide me soon as possible because i want to join new job and without that certificate i won`t get job.
