Earlier they provided free data and calls to lure customers to join them, they bought a revolution in the telecom market, no doubt. But now their service charges are rising steeply, and their service quality is detoriating proportionately. And they did a unfair marketing by putting up PM’s picture in their Ads earlier, to get more customers and brainwash them to use their service, so that they could have a major stake of the customers that use their service once.
It’s really better to use another ISP’s service, because their service are probably not going to improve sooner ( or later) .
