I've just receive this email from a business friend who works for an international Company.
"Subject: FW: Parcel Scam
This is a genuine warning, which you might not have already heard about.
The Trading standards Office have brought the following scam to our attention:
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 ICTIS (the premium rate service regulator) at http://www.icstis.org.uk or your local trading standards office.
This is a genuine scam.
This service is under investigation by ICSTIS. Please be aware of this scam and forward this information to as many as possible."
I think they are mainly targeting large businesses but you never know. I don't think that they care who they get their £15 charge from.
