Sales and ordering friendly, helpful, and proactive. Helped me sort the paperwork to get the rebate. From there on, total disaster. String of late cancellations for fitting appointments, combined with an inability to get dates right. Then an appointment with a half days leave taken they simply didn't turn up to, without any information being sent. Fitting re-arranged for a few days later on a Saturday, but the engineer lacked knowledge on earthing (or modern regulations and standard practice, it seems), so left with the unit installed but not connected..... Move forward 2 weeks, with endless phone calls speaking to people who couldn't help / put through to anyone who could help / provide any useful information, unanswered and unacknowledged emails, before finally sorted out and connected. I think final action due to making lots of noise on twitter. Dunno. Anyway, the unit now working, neatly installed, and appears to be fully functional, 2 months after placing my order.
