Anyone facing issue with Airtel inflating bandwidth usage?

Mailed them.Phoned them.Tweeted them.Lets see now.

In the mean while some idiot airtel technician did "maintenance work" on the box and line and has messed up my connection.
 
Got a waiver of rs 1129 on my bill.
 
Why is airtel being so generous :O

Have you got a solid alternative in your locality?
