Airtel — Lack of proper customer support

I am a postpaid customer of airtel of Kolkata ( my no. is[protected]. I generally use this connection for internet surfing. I am using 999 unlimited plan. It was working fine at Calcutta. But it is not working at Bangalore. When I try to connect the internet with the help of the airtel dialup box, it shows an error stating "you cant connect before register an avialable network". Even when I am putting the sim in a cell, I am unable to select any network. The sim is not being detected by the cell.

I have called up the Bangalore customer care and after knowing that my sim is registered at Calcutta, they assured me that the Calcutta dept will contact me the next day as the Bangalore Support does not have my data with them. But Airtel has failed to contact me the next day.

Then I went to the Customer relationship center at Indira Nagar (bangalore). They said they cannot do anything with a calcutta customer since they are unable to access the database of Calcutta customer. They instructed me to contact the Calcutta support team.

I contacted the calcutta support team. It was a STD call. I was told that I need to put the sim in a GPRS ebabled cell and activate the sim. I did it but it did not work. The CC Executive also informed me that my scheme is 350 while i applied for 999 unlimited scheme.

I have also written to [protected]@airtel.in but they have not replied. It is not possible for me to contact the Calcutta customer support as it would be a STD call. I am very fed up with their service.
