AIRTEL BB
When it works it is good. When breaks down and if you complain , it is definitely attended to ,quickly, within a day.
Most often it breaks down, due to their own maintenance activity, but they never inform you in advance. When you tell them about break-down on 121 , initially they'll talk tangentially as if they do not understand what is the problem, if you get angry with them , they'll say there is no problem from their side and we have to check at our end , if you threaten them then only they'll tell you that there is some work going on and it'll be restored within so many hrs. This is the black mark on AIRTEL BB and if they
straighten this bad trait in them,they'll certainly be the best in India.
