Balance deduction

Please what is house of model service??? I don't know it. I got a message that reads ''you successfully subscribed to house of models.'' Meanwhile I had not dialled any short code or sent any message. My balance was deducted and I was very upset. Automatic subscription for a service that I didn't even know. I saw a text message in my phone and quickly called to disactivate it today on friday 15 April 2016. I was told I subscribed to the service but why will I buy something I don't know anything about?? What codes or messages show that I subscribed the service myself?? Well if it happens again, I will just throw the sim card away and buy a new sim card from another provider.
