Postcode Lottery Voucher Scam - Beware of Scammers

I just received a call from "Postcode Lottery" claiming people in my postcode have won a discount card for a number of shops and a voucher for a Villa break. They confirmed my postcode without me telling them, but they then asked for my bank details to deposit 1p in my bank to activate the card. I of course declined and they hung up. I called Postcode lottery and they have confirmed it’s a scam and they clearly have all the RG postcodes and working down a list.
