I have just received this email. I don't know how true it is but I am posting it to you anyway just in case:
Subject: Postal Scam
Royal Mail postal scam.
Can you circulate this around 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 £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) athttp://www.icstis.org.uk
