Hi, I had 2 guys knocking on the door with npower badges tonite, and he gave me some dribble about we are here to see if you can get cheaper rates for your property. All we need are you latest bills and see if the account numbers match what we have on our list. The whole thing just smelled of a scam. I am not with 'npower', and i said no im too busy and he said well people will keep knocking till we have those number for checking. Now all they really want to do is switch people over to their company on the sly, and many people will fall for these kind of tatics, especially old people. Now why would these door to door idiots want any billing information from people, if they are from a legit company, they would have access to the information in the first place. I bet they want you to sign something after!. So am i right this was probably a scam?. And i supose nothing can be done to stop it, and you know they will knock on all your neighbours doors and most of them will give them the bill for inspection.
