Retired — MTNL Landline not working last 2 months

Address:

803c Luxmi Bhavan, Dadar East, Mumbai 400014

My MTNL landline is not working for the last two months. I have made several complaints & am given the same complaint number. Finally i went to the office during COVID times to talk to the manager wadala exchange. I am 83 years old had to climb 2 floors to meet MR Wilson Nadar Dy General Manager Kulkarni & he agreed to attend to me complaint. Its been over 1 week & till today my phone line is dead. My bills every month is being directly deducted from my bank account. How do i get a refund from MTNL & get my landline working. I am a retired man who is 83 years old who has to keep going to MTNL office, does MTNL have no consideration.
