About 3 weeks ago my son showed me a text on his phone saying the following: Free Msg: You are subscribed to Topvids for £4.50 per week from topvids.mobi HELP? It also give a phone number 01183244333. I deleted the message and ignored it as his phone contract was due for renewal the following week. He's now got his new phone and tonight got the same message again. I've googled it, and it's obviously a scam, but there's no details on how to stop it that I can see. I need to contact my bank on Monday, and I'll also be contacting EE. Does anyone have any tips or experience on how to deal with this?
