Airtel
Recharge amount is not credit to prepaid connection

I have done the recharge of Rs.200/- for my prepaid connection in Airtel. But the amount is not credit towards my prepaid account, when i am calling the customer care, they are telling that the amount was credit towards 3G data as I dont have 3G connection with Airtel. Now a days Airtel is alwasy cheating and doing the same for every customer. This is not first time for me.
