Airtel is the worst dth. They (airtel dth) connect very fast in 1st time but after that service from airtel is horrible. Connectivity issues are often, service engineer not available at all.Normally, nobody check balance, they deduct more some time. Checked & found Rs.140 more deduction unwantedly. No any airtel executive can explain . They give numbers which does not exist or will ring, nobody will pick call. Even avoid when told to return the amount. Suggest if port possible from airtel dth.
