for my mobile number i have activated the hello tune on 1/09/2009 but till date they have not activated the hello tune and if i call them they are keep on asking for extending the time from 01/09/2009 till date. i have called them for more then four times and even at the last time when i called them i requested them to even deactivate the hello tune but they are not activating or deactivating. they are only charging money and till date my tune is not activated. i am very much frustrated because of this guys. they are cheating the people like wise and withdrawing the amount from the balance. please take necessary steps on this airtel network to save peoples from getting cheated in future.
