I encountered the same problem. Received a text message from nowhere saying that I am subscribed to some service and have to pay a weekly charge of GBP 3.75 unless I put a stop to the service. I immediately sent a stop message. I deleted the text message and forgot about the matter. However, when I received my phone bill, Iwas surprised to note that I got charged GBP 3.75, 3 lots of GBP 1.25. The bill showed that these items were charged prior to the charge for sending tbe stop message. When I rang my mobile operator THREE to enquire about the charges, THREE said that these messages were from an organisation called Zamano. They tried to contact Zamano on my behalf but couldn't get through . They gave me an email address to write to them. I have written to them complaining about the charges. I doubt whether I will receive any refund. How do you put a stop to this kind of [problem] when out of the blue you receive a message on your phone and unknown to you, get charged for a premium service that you have not ordered or requested in the first place? Isn't this the responsibility of the mobile operators? I suppose they can't be bothered because they get a cut from the [problem].
