Postal Scam:

Please circulate this, especially as Xmas is fast approaching - it has been confirmed by Royal Mail. The Trading Standards Office are making people aware of the following scam:

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 £315 for the phone call.

If you do receive a card with these details, then please contact Royal Mail Fraud on 020 7239 6655.
