Hey mate I saw your post about theft of your pictures, i had a chat with one the guys in my team he had a look the company that regulates premium number is
http://www.phonepayplus.org.uk/ so you can contact them and talk to them about it if you can persuade them they will stop the service, I had one of the guys look into it a bit more and he said there is a phone number 08450261060 that belongs to the same regulatory body that deals with this kind of stuff. I hope it helped, good luck mate.
