Airtel — Pathetic services

There are 3 problems I am facing.

1 Coverage issue While talking the phone gets disconnected. However I see full network. Many times call gets connected but reciever cannot hear the voice All thses calls are getting charged.

2 Hello Tunes : Many times the Hello tunes get changed randomly. When I have choosen a Hello tune and paid or the service how does it get changed randomly. Secondly When I am on a call and there is a second call coming, why does a Hello tune play. Waiting message should be played.

3. Mobile Office : I have suscribed to 399 / Month Internet usage on mobile. I cannot understand why only 100 MB is kept free. There are so many Airtel suscribers that I know are using this service for 199 / Month with unlimited download. Moreover how am I suppose to know how mucg have I downloaded. This is something that has to be addressed. If the usage at given point is not known how are suppose to limit the use

I hope all my queries will be addresed. I have been associated with Airtel right from its launch in Mumbai and hope for such small glitches I would not have to discontinue.
