Airtel — outgoing calls stopped due to nonpayment

Address:

Kolkata, West Bengal, 700149

Since yesterday, 7th nov 2017, my outgoing calls are getting stopped abruptly for few hours and again it is getting resumed. This has happened today as well i. E. 8th nov 2017. The reason is non-payment but my connection is prepaid and i have sufficient balance in my account with validity. Infact my internet is also working properly.

This is really ridiculous. Please see to this matter because this is this is hampering smooth working.
