BSNL — service activated without my consent.

I am an bsnl prepaid customer with mobile no [protected]. I recieved a call from +[protected] today. It was asking to subscribe story book. I cut the call immediately. After that i recieved sms from 57171. And 5 rs deducted from my account. I called customer care at 1503. Customercare cut the phone saying that if you cannot talk in english than select hindi option after dialing 1503. Now no customer care is picking my phone. At last i have stopped this service by dialing *777# as it was activated without my consent. I request bsnl to refund my deducted amount.
