Airtel — Worst broadband service ever

My landline number 4051593 associated internet has been very very bad. Everywhere Airtel provides 100gb to my area which is main in my city Salem they are providing only 2 mbps speed n that too keep disconnected last two weeks the connection was very pathetic. And also with kids exam goin on and repeated request to keep the connection good exactly on exam time the connection got very very poor and affect my kids one in higher grade none in lower grade exam by missing 20mins of their time. No response where ever i complain. Worstest service ever provided by Airtel. I was promised to increase the speed in two months it’s been 1.6 years yet no steps taken to increase the speed. Airtel is looting the customers n loosing its bloody reputation. Airtel is taking us backwards than forward. My kids n me are mentally hurt by their bad service.
