Shoppers Discount
Payments I did not authorise or ask for

I have been billed on my credit card (BARCLAYCARD) for four months at £10 per month and have no recollection or odering or receiving any service whatsoever. I have been receiving mails from Shoppers Discount, but, as they were unsolicited I delete them whithout reading them. As a result I have consulted my Credit Card Company and I have the problems of having to have a new card.
