My wife has some learning disabilities, she saw the advert on Facebook to win vouchers for tesco, asda including rubbish stories of people who had apparently won. To cut a long story short over £40 was stolen off us by these people but through our contracted phone company (shame on you o2). I made the calls to o2 who where unfortunately not very helpful apart from giving me the telephone number of these people. I called and was confronted by an arrogant girl, I went on to say that my wife who had some learning disabilities entered via Facebook for the so-called competition not realising she would receive texts costing us £3/£4 each. The girl was no help at all obviously, and said we wouldn't get the money back.. Disgusting! In this day and age how they get away with it is unbelievable and again to the phone companies, shame on you! Friendly advice Don't enter any competitions, you will just be robbed of money and very little you can do about it. Please spread the word and make these thieves known.
