I have included a pic of the window advert on my profile, for those who were asking to see it.
Have since noticed after fitting, they damaged the ceiling light, the bannister and scraped two walls. So have reported them to Trading Standards, as I feel like I gave them plenty of chances to redeem themselves. There was also no apology from the manager when he fitted the carpet.
(Disclaimer: I know this isn't an AIBU, but I thought I would update where the original thread was).
