Airtel — rs.150 charge for engineer visit

Address:

Gurgaon, Haryana, 122001

Now days airtel dth charging rs.150 for an engineer visit, even if there is no problem at our end.
And every month we are facing issue on average 150 per month expense added for dth engineer visit, plus loss of days for dth service in these visit.
Which also paid. For example
For 30 days payment, if any issue come 3 days service was lost, 150 paid for engineer visit. If you calculated for annually basis. 150*12= rs.1800
3 days lost in month= 3*12=36 days which make 1 month lost.
Overall rs.1800 and 1month lost (Which ipaid for services and couldnt get due to service failure).

I requested please look into this matter
