Says they are calling about electricity offers. When pressed, he said the business name was Benefit Deals. There is no business of that name coming up on a Google search. He hung up on me.

Received call from these guys who claimed to "give you a better deal on electricity plans by looking at other companies" however didn't state actual company name. Clear time pause on answering call suggestive of overseas call centre. Could hear others talking in background. Eventually got them to hang up on me :)
