I have no idea how they got my mobile no, I do not understand these things, they keep sending me messages saying $34.30 spend reached, I did not know I gave them any money, I want it all to end but although I reply to the sms message saying this, it just comes back as not having been sent. I am a senior citizen & very worried about this, no-one I know can offer me any help, not even the vodophone people. Can you help please?
