BSNL — MASTI PACK ACTIVATION WITHOUT CONSENT

Address:

Thrissur, Kerala

Sir,
I got message 56505 on[protected]"Thank you for continuing monthly masti service. You have been charged Rs.5" on my bsnl No. [protected]. Which I have never subscribed. I have registered a complaint at 1503 (bsnl complaint registering sms No) but there is no response from bsnl.
So i have tried to cancel the subscription by sending sms
"CAN MASTI" to 5605
and the reply was
"To confirm your subscription cancellation reply with "CAN MASTI YES"
so i replied.
"Thank you for using our service. your unsubscription request has been accepted"
The subscription was cancelled but they have charged Rs.3 for each sms.
Total loss is Rs. 5+3+3 =11
This is an illegal and fraud. Is there any chance i get my money back and make sure that they did not activate such packages without consent.
kris.
thanks
