Reliance Communications — Unwanted subscriptions

Dear all
This is to inform you that Reliance communications is automatically registering Caller tune subscription with out the knowledge of the customer . & a charge of 30Rs is deducted .
I had faced this issue 2 times. Both times on my Prepaid connection,
At 1st time, I noticed that when some one called me, he was hearing reliance official caller tune, that was how I came to know . & when i checked my balance around 30 - 45 Rs was deducted .. Since i was unaware of this it was very late when I complained back.. so they promised to credit back amount on prorata basis ..

The second time I got a message on my prepaid mobile that I use very rarely( which is almost OFF all the time ) that " Thank you for subscribing to Caller tunes... & u'll be charged Rs 30 / 30 Days..."

Immedietly I called Customer care to enquire .. many time I was unable to reach the executive on my 6th attempt I got the executive & informed & raised a complaint ... But she was not able to transfer my call to Caller tune dept.. But still she confirms me that, It was accidentally raised for a customer & the whole amount will be credited Back"
Waiting for the credit - I belive this may be done.. But in case I had not carefully read the message I would have lost some money unnecessarily

Dear all customers pl take care of this
