Was telephoned by this number, a man speaking good English who offered a better tariff for gas and electricity who knew who my supplier was. I NEVER negotiate or buy anything offered to me by post, telephone or at the door, so I politely dismissed him. Was it a scam? Who knows but irrespective, he got no joy. The level of success these guys get must be low. If they had any brains at all, they wouldn't be doing this sort of job anyway.
Man rang me saying from Eon who had taken over Npower. He wanted me to switch accounts for a better one. I told him would think about it first but he said the takeover was happening now. I still did not take him on as I was suspicious.
