Airtel — Outgoing Calls Barred On Prepaid SIM

I've been a customer of Airtel for more than a decade now and all of a sudden, as of this morning 12/7/22 all outgoing calls have been barred with only incoming and internet working.

I've raised multiple complaints and tickets to no response and pathetic customer care.

Apparently it will take more than two week just to review and resolve my ticket, such fools of the highest order. It is impossible for anyone to talk to a customer care agent without wasting hours on the IVR which is useless and provides no resolution.

The IVR redirects me to submit a complaint via the app, with no human intervention and no option on the IVR to talk to anyone and explain the severity of the issue.

Worse, on calling the IVR says non-payment of bill(not sure which one as I'm prepaid and have never availed any other service) is the reason my outgoing calls are barred.
