Tata Docomo — Reducing Balance automatically

Address:

South 24 Parganas, West Bengal

Sir,
From last few days i am charging for caller me tunes automatically. It was happened i got a message from docomo for dialing some number like ^^^*^^# (^ are numbers) for getting free caller tunes for 3 days , and the song was "Pungi".When i dial that number then it was showing that it will be charged for 30 Rupees for 30 days, and press 1 for continue.
Then I press cancel switch. and from that days Docomo started pressure to get the caller tunes. the send me a sms that i subscribed that tunes and they charged 6 Rupees. When I contact with customer support they cancelled the caller tunes and say sorry for the fact.But after few Hours it is Happening again. They automatically activating the caller tunes and deducing my balance from last few days continuously. last day i spend all my money and they send me a balence for low balance the service is stopped. But when I recharged My number then they again started the same thing
and I am bored about this. i send a complain to their coustomer support but they did not take any step. They said it will be ok within 48 hours. but it is still happening.My TATA DOCOMO Number is [protected] and the complain reference number is 485971. they still doing this and i think they are forcing me to take their value added service and pay them whatever they charge. Please Help me , I am scared to recharged my number .
