I was offered an earlier installation by Chargemaster for a Sunday. I accepted this as it was agreed verbally that this would be an afternoon installation. When this was finally confirmed the email said installation would be between 8am and 12pm. Not what I'd agreed. I couldn't get it changed as the office had closed and it was a Friday evening before I saw the email. This was frustrating. However not as frustrating as getting up early on a Sunday, waiting for the engineer to contact me and getting nothing. When it'd gone past 12 and I hadn't heard anything I tried contacting Chargemaster. Sadly as it was Sunday, not one was there to take my call. I complained by email and first thing Monday morning I received a call to say the engineer didn't turn up because a system error meant they didn't get the job. The person I spoke to had no sympathy that I'd wasted my Sunday waiting for no one to turn up. He rearranged the visit. When the engineer did turn up, he was excellent. Really friendly and very helpful. He also managed to install the charging point exactly where I wanted it to go and with minimum disruption. Top marks to the engineer. If you're having a charging point installed, avoid a last minute change to your installation date. Especially if you're offered one at the weekend. This should've been a "very good" experience, but because you can't speak to anyone from Chargemaster at the weekend and the call centre person seemed to have no sympathy for me wasting a da, this only gets "acceptable"
