BSNL — outgoing calls of bsnl prepaid barred

Address:

Ludhiana, Punjab, 141106

The outgoing calls of my bsnl prepaid number [protected] is barred from 10 jul 17. It is causing lot of trouble to me. The number was initially postpaid. I got it changed to prepaid after portability. When spoke to customer care, i was told that the bill of apr 17 was not paid. Customer care advised me to pay the bill and contact nearest exchange with payment receipt. I did the same. But number is still not working. I am facing inconvenience. Kindly do the needful.
