A bloke from this scum company - www.moneyexpert.com called at my mum's door this evening at approximately 20:30.
He said households in the area had been over changed and had been sent to fix the billing problems.
He sounded very official, but I realised he was just trying to get us to switch to get a fee.
My mum has a Devon & Cornwall Police no cold calling sticker on the door which he completely ignored and I had to tell him twice that we are not interested before he got he message and left.
Hopefully posting this will forewarn others.
Please
