i found this on another site. you have been warned!!!!!!!!!!!!!!!!!!!
Please be aware as Xmas is approaching. A card is posted through your door from a company called PDS (Parcel Delivery Service) suggesting that they were unable to deliver a parcel and that you need to contact them on 0906 6611911 (a premium rate number). DO NOT call this number, as this is a mail scam originating from Belize. If you call the number and you start to hear a recorded message you will already have been billed £15 for the phone call. If you do receive a card with these details, then please contact Royal Mail Fraud on 02072396655 or ICSTIS (the premium rate service regulator) at
