Airtel Prepaid — activation of paid services without our interest and intention

Address:

Rangareddy, Andhra Pradesh

I'm air-tel prepaid mobile user ([protected])for the past 6 years.
On 06/10/2012 3 services were activated on my mobile without my intention
1) ASK AN EXPERT ABOUT YOUR CAREER AND JOBS, for 30 Rs/30 days
2)ITEM SONG for 10 Rs/7 days
3)GAMES for 1 Rs
and when i tried to contact their costumer care on 121 and 198,the call is getting disconnected saying that i should dial *121*4# to manage my services and no customer care person would talk.
when i talked with their Internet customer care they said that it is not in their department and should call the customer care on 121.

This is not the first time air-tel is doing this every time they would be deducting money in the name of one plan or the other.
Fed up of this money thirsty worst network.
