Terrible customer care and guarantee is only helpful if you're happy to wait weeks. 3 weeks with a door that won't lock and several mistakes made. Our door stopped locking on a Thursday, I called straight away, the earliest they could come out was the following Tuesday, fine. The engineer measured the door and left saying they will call within the next 2 weeks. I called again straight away, they booked me in for the following Thursday to fix, 2 weeks with an insecure house is not ideal, but fine. Engineer came with the wrong part🤦‍♀️ and left, door still not fixed. I called again straight away, they rebooked me for the following Monday.. engineer came with the wrong part AGAIN. I called again straight away and they said they'll send someone out on Thursday. Three weeks with a door that won't lock and Anglian wouldn't cover the cost of a locksmith to get it locking until then. On top of that everytime I have to call it takes at least 20mins to get through, when I did get through the last time, and spoke to managers Lee and Carl, they were dismissive, rude, and had the cheek to question why I had got uptight by the last conversation. I think after three weeks and two messups I was perfectly within my right to be cross!
