You think that's a pack of lies!
The biggest pack of lies is that although it is true that many years ago they got double glazed by Everest, a big feature of the ad was that they came with a lifetime guarantee never to need replacing. Well, for some reason, they did need replacing, so the owners contacted Everest to ask them to sort it out. Everest didn't want to know and told them that. It was only when legal action was threatened that Everest realised they had made such a fuss of the guarantee and were over a barrel, that they relented. I get the impression it was like a reciprocal arrangement where the owners got new glazing for nothing and Everest covered their backs (and costs) by doing another ad. Whatever, I am not impressed by Everest or this ad.
