Airtel — internet data scam

Address:

New Delhi, Delhi, 110001

In india all cellular company making fool to peoples. I don't know tri are also involved or not. Everyone can realise that before to 4g. 3g speed was awesome and after 4g come in india suddenly 3g lost his speed. Mean is that 4g became 3g and 3g became 2g.
One more interesting think is that company's sell 3g on 4g rate and say that we give 4g for 80 days.
Something big wrong in this scam
