The message is, no matter how enticing or honest the offer seems, have nothing to do with it. Just delete all emails and NEVER open an attachment from someone you don't know. Put the phone down on unwanted phone calls without speaking to the caller, recycle all unsolicited mail and tell doorstep callers to go away. The taxman, banks, electricity and gas companies will never ask you for bank details, such as account numbers or pin numbers, over the phone, by post or by email. So, if that happens, it's a scam.
Gerry is trying to establish Cold Calling Free Zones in Wales where communities have official signs saying that cold callers are not welcome. This works and deters all but the most audacious.
Just remember, if you want your drive paved, new double glazing, a walk in shower, or anything else, always find the supplier yourself. that way you will keep yourself safe from these criminals who are trying to part you from your money.
KEEP SAFE !!
