Airtel — airtel postpaid sim not get activated from last 2 days

Address:	Hyderabad, Andhra Pradesh, 500072
Website:	www.airtel.in

I've converted from airtel prepaid to airtel postpaid. I have submitted all required documents on[protected] but till now postpaid sim is not got activated and for verification am trying to call 59059 but not connecting. From last six hours i am not getting signals and every time i try to call at 59059 it automatically disconnects and also i'm unable to receive incoming calls to my number. I couldn't believe how airtel is so weak in customer service.
