Bharat Sanchar Nigam [BSNL] — outgoing calls not available even when bills are paid every month

Address:

BSNL main office ,near Main post office,wardha

Since we are having mobile phones at home, we were not using our bsnl landline since last year, but we were regularly paying bills every month to keep the connection regular just in case.
Few days ago we tried calling to our relatives and that's when i noticed our outgoing call service was not available. The auto response was saying "your call cannot be proceed. Due to non payment of bills". But we are paying every month bill regularly on google pay. We tried many times for consumer support but outgoing is still not available. Incoming is on.

They asked us to call on 261038. After calling them they gave us another number to call. After calling on that number they said "it's technical section, it's not our section to solve your problem". We contacted on above number again. They checked for previous all bills were paid and again told the same thing to do and talked irrelevant to get rid of situation without solving problem.

We just want our landline service to be get regular.
Our latest bill is paid with cash on 21/05/2020 on counter with billing amount ₹294
