Her number would of been put into a Premium service manually via internet or texting.
Contact CRTC
http://www.crtc.gc.ca/eng/contact.htm , tell them what happened.
Then ask your Carrier to take off the charges since its the first time this has happened. If they say no , then just say you have talked to CRTC and reported this ... 99 percent of times they will knock it off. Also ask who is providing the service and the contact number.
Hope this helps.
