We requested a quote from Everest to replace all of our doors and windows in Aug 2021. Their representative attended on a weeknight evening and we advised at the beginning that we weren't going to make a decision that day and explained that we'd had a bad experience with another double glazing provider in our previous property due to pushy sales tactics. The representative advised that they don't do this and would just provide the best price they can. What followed over almost 4 hours was the most drawn out process of measuring windows and providing technical demonstrations of windows and doors far beyond what we cared to see. This was finally followed by a quotation for a quite ridiculous £38,000 for the work. We stated clearly this was far too expensive and at this point in the evening we simple wanted him to leave but instead he became somewhat belligerent and refused to take polite requests to leave (by now the time was past 10.30pm) and only finally left when we carried his items to the front door. Everest, your sales tactics are poor and your representative blatantly lied about his intentions at the beginning of our visit. We'll be using a local firm we've used before who Everest were 3.5 times more expensive than. It's also worth noting that this alternative firm measured, discussed options and left in a little over an hour, not the 4 hour time wasting Everest employed. As it stands your sales approach has clearly backfired here. Your representative has wasted 4 hours of his time. We will NEVER purchase from Everest windows and never allow one of your representatives in our property again. Change your sales tactics, your product might be good, but how you sell them is disgusting.
