I arranged for an engineer to come to our busy shop and was told someone would be with us by 3pm, I called at 2.30pm to confirm that someone was coming as I hadn't heard anything and was told yes, I would get a call when he was on his way, but it would now be in the afternoon between 3-6pm, I was then rung at 5.30 to be told he was delayed and wouldn't be attending today. Sorry for any inconvenience but they could rearrange for tomorrow! I explained the inconvenience and cost to my business, and I advised that the service was terrible, at which point instead of apologising, I was met with "okay, goodbye" and then the phone went dead. Disgusting. Do not recommend.
