My Mum does not know how to use a computer never mind shop on line ! they were abroad on holiday ( and did noy use the card at all they are so careful about using it and only when it is necessary )and came home to find about £7500 spent on their credit card !It took months and lots of paperwork and phone calls to finally sort it all out ! They are OAPs and to this day we dont know how they got hold of their details and abused it in this way !
