Airtel — Delay in prepaid to postpaid connection.

Address: Bangalore, Karnataka

I have opted for corporate postpaid services from prepaid on  24, Aug 2015 and have submitted all the documents regarding the same. Although Address verification is completed and I have received the message for same still there is no network.
I have tried contacting the airtel outlet as well they assured me that issue will be resolved in 4 hours still nothing has happened.
Upon calling customer care they update that outlet have made "minor spelling mistake while typing in the billing address". Minor mistake Really!!!.
This is not the behaviour expected from airtel.

outlet:Vijayanagar, Bangalore
