A lot of things went wrong. Initial appointment booked for between 3pm to 6pm. Nobody turned up and not even a phone call. Said someone will be there the next day. Engineer turned up the next day. For something that should have taken 15 mins to diagnose took almost 45 mins. Got the feeling that the guy was just wasting time. A part was identified that needed replacing on the hot water cylinder. Discussed with the guy and told him that they should get it ordered. He agreed. The same day I phoned the company and they said I was supposed to order the part, I told them that it would be better they ordered so that we get the right part. They agreed to call the engineer and get the details and will order. After several calls there was still no response and part was not ordered. They never return calls and after 2 days there is still no response. A totally incompetent company that I would not recommend.
