Airtel — transfer from prepaid to corporate postpaid

Address:

500055

We have a connection [protected] which was taken at the time of inception of airtel in india. It was a post paid connection in personal name. We wanted to transfer this into our corporate account. We were advised to make it prepaid and then transfer it to the corporate account. Past 2 months the connection has been running as prepaid. We have made several complaints but till now it has not been converted to postpaid corporate account. Every time we are said that it will be done by evening or in 48 hours but it has not been done.
We request you to kindly look into the matter and help us.
