Initially service was good. An engineer came out quickly assessed the problem with my boiler and said that they would order the part and return to fit it. I spent the next day trying to find out when this would be through the call centre and was consistently advised that the plumber was on a job and I would be called back later. The forth time I called I was advised that the engineer was not working that day, so there was obviously no chance that he would be returning, but they would chase it up and call me at 8am the next day to arrange the repair. Day 3 - no call so spent another 20 minutes listening to Enya before speaking to another advisor who initially tried to fob me off with an imminent call back, but did speak to the engineer who said there was no chance he would be out today. Still waiting for a date. Very inconvenient, zero customer service.
