BSNL — unsolicited -MOBILE service on "WAP Bollywood "

Address:

Dhenkanal, Odisha

Dear sir,
My prepaid Mobile No. [protected] has been unsolicitedly SUBCRIBED to "WAP Bollywood Subscription Pack " by a Service called BV-ONMOBL, since early June'2012 .
Evey 10 days a messkge comes saying " Subscriber , your WAP Bollywood Subscription Pack will be automatically renewed on .." and gets renewed after 3 days given , at a charges deducted @ Rs 10/10 days . Now I received same message saying it will get renewed on[protected] message recived at 01.06.45am today .
How and why BSNL allows such subscriptions and allaows pre-paid balance gets paid to these services without giving any OPTION to "UNSUBSCRIBE" such unwanted service in their network.
I request BSNL, Orissa to discontinue the above service from my No [protected] and oblige . Now I am staying at Gujarat State and still likes to have this no to continue as it is BSNL, if this wrong subscribed service is removed .
With reggards,
Santhosh Hegde
