Same thing happened to me today. Browsing Facebook on my phone, pop up came up, clicked on the cross in the corner to close it and immediately received a text saying thank you for my 1 entry at a charge of £6! I am disgusted that this can happen so easily, and since googling this incident, have seen this happens quite a lot. I will be phoning them to ensure I have my number removed, as there is no text option to reply the usual 'stop'. Will also be reporting them to everyone I can as this should not be allowed ????
