First of all I want to say that I am not happy with airtel customer care service. They had cheated me . I had an airtel simcard. Airtel compuny cut my 200 balance without any reason. Whem I contact the customer service number they tald me that ur money will be credited in your account soon. What is this ? If I had not called cuatermer then my money will never refunded. I have done portability after this insidant. This is airtel.
