Reliance Communications — internet not working and balance drained without calling

My internet is not working properly. I took a 180 day internet pack of 1gb daily net but last four days net is not working and today it goes off again and again. My phone had 500 rupee talktime balance and rs 103 were deducted due to vas service which I never started and rest rs 397 drained due to unknown reasons. I called 198 many time but customer care executives never take call. Kindly address.
