I have had a number of calls this week, indeed two today who replace the phone when confronted by the call screener. I rang it back just now. Its some crowd calling itself Energy saving Hub. Obviously English. They ignore what you tell them and are pushing to get people to let them give yoyos a free loft insulation inspection. They infer they are government funded, but avoid any direct questions. They use the old news that Fibreglass can be an irritant, like who does not know that?. When you tell them it was done under a government scheme they then say if its more than 18 months ago it could still be out of date. In the end I just could not stop her blithering in my ear so put the phone down.
Its probably some fly by night mob trying to get a foot in the door. They got no info from me and in my view if they cannot be bothered to use the call screener their bottom line is profit or scamming. Brian
