If you are a customer of airtel prepaid USA call India then be careful, keep checking your account (money) regularly. They are deducting extra money on each call. It happened with me today itself. They deduct $0.02 extra. When I called up their customer support. They accept there is a mismatch of figures and glad that they will take action with in 24 hours. Let me see. Its by chance I calculate the money today. Otherwise I do not know since when its happening. Be careful. I wish if I could have sunil bharti mittal email id/phone no? Would like to talk to him about this issue. Its disgusting.
