Airtel always activating Value added services on my number without my knowledge..i am getting sms as some services activated on my number and some amount was charged for that..when i complained this to customer care they always replying that i am only activating services...i asked for refund of the amount deducted but they said they couldn't do that...so i decided to port my number to some other network..if we have main balance in airtel number they always deducting it by activating VAS without our knowledge..its also a kind of theft only
