Airtel prepaid mobile service
No incoming/ outgoing calls

I had changed my service from postpaid to prepaid. But even after submitting all the necessary documents many times, I am unable to receive or make calls from my mobile phone. It has been a month now, but still this problem has not been solved by the concerned people, even after filing many complaints with the customer care, and the local vendor as well.

My phone number is 9960335533
