Bharat Sanchar Nigam [BSNL] — deactivate bsnl hungama services, which is activated without my consent

Address:

Amravati, Maharashtra, 444605

I got a phone from bsnl they ask me any complaint of bsnl broad band services i said about the low speed of broad band they said send sms bvas at 56677. I send the sms and i got the reply that my no. Is incorrect i. E. Not registered. After some time i got 3 to 4 massages from bsnl hungama services that i have activated the service and it;s bill will come along with broad band bill. This way bsnl hungama activated their hungama service from me and they cheated me. I want to deactivate the service on immediate effect.
