Apparently some Neighbourhood Watch groups are circulating details about a scam where someone claiming to be from BT calls and threatens to cut you off if you do not settle an unpaid bill there and then by giving them your credit card details. The details are in this document. It’s a real scam apparently, and it’s your credit card details that they’re after. BT have information about it on their website and it is covered by internet ‘scam-buster’ sites such as Hoax Slayer. Be vigilant!
