Mahanagar Telephone Nigam [MTNL] — Broadband, Landline dead since 4 months

My landline phone and the broadband service is down since 4 months now. I have made repeated complaints many times. NOBODY, not a single person came to even check the problem. The helpline lady keeps giving random mobile numbers of service engineers, none of which gets answered, then she says "oh, he might have got retired, try someone else". then same thing continues to happens for each number. It seems that the whole MTNL Mumbai has taken retirement and after lockdown I haven't seen any MTNL guy in the area as well. The only things that's working is the billing department I guess because I am getting the bills regularly all this time. Please at least make a public announcement that the company has been shut down and they only exist to collect bill money.
