Airtel Data Card — Data Card is blocked and no one is to guide to restore it

I bought the Airtel Datacard on 14/4/2008 bearing number [protected] and SIMnumber[protected]. Initialy it took nearly a month to start its operation. Thereafter I hard used for nearly one and a half month that it started giving trouble.
I made a formal complaint with their Customer Care Centre on 12 July 2008 which was attended by Ms Simran. Later on 17 July 2008 I discussed the matter with Mr Kulwant Singh and later with Mr Tarun Tewari and Mr Aashish. It 4.57 PM the Data card started functioning, BUT, in the evening once again it start giving trouble and it was connecting with the remote computer. I called on again on 17 July 2008 at 10.32 pm, which was attended by Mr Mohan Tripathi, who informed me that the fault is at their end, and there is some problem with wireless connection due to congestion and also some mismatch with the wireless system. Mr Mohan assured me that he will contact with wireless department, and the data card would be made effective within half an hour. It started the next day.

Later in August it again started giving trouble and became unfunctional. I called on on 6 Aug 2008 at 1000 pm, which was attended by Mr Ranjan, and I was informed that the Number (Service) is barred. Since then, I am trying here and there, but of no use.

It will not be out of context to mention here that ever since I purchased the Datacard, no bill has been forwarded to me for payment. In spite of my regular request to the agent who supplied me the Datacard, no bill has been issued to me. Virtually, I did not used it to its true value.

MAY I SINCERELY REQUEST YOU TO KINDLY DO THE NEEDFUL TO MAKE THE DATACARD FUNCTIONAL.

Trilochan Singh.
