Airtel — i'm complaining about the adof games which unnecessarily reduced rs 120 from my balance even if i didn't activated it.

Though i didn't activate the adof games subscription they activated it and and rs 120 get deduced from my balance and when i connected to help line number, they commented that your balance wool be refunded and some if them said that it wouldn't and today when i called them after one day then they said that your balance wouldn't be refunded... What the hell.. Without any action of activation from our side they reduced the balance on their own... Is this what they do with customers... Really hateful airtel...!!!
