I am with Tesco Mobile. For a period of over a year a company under the name Text250 kept sending me messages every week about their text service even though I told them I could not use it as they did not cover text messages to people abroad. Finally, Tesco Mobile whose help I enlisted as I noticed that my credit every week kept going down without having made any calls explained to me about premium rate text messages from this company whose name is 2ergo, who were obviously deducting money from my credit with Tesco Mobile. They managed to put a stop to it, but my claim to the text company to refund my money for the unauthorised deductions has fallen on deaf ears. They were deducting £2.50 a week subscription and over a year I am out of pocket by more than £255.00 for this unauthorised deductions.
