If you find a card posted through your door from a company called PDS (Parcel Delivery Service) saying that they have a parcel for you, do not phone the number given on the card. It is a premium rate line and will cost you £15 for the phone call. Contact Royal Mail Fraud on 0207 239 6655 or ICSTIS (the premium rate service regulator) at www.icstis.org.uk
