Very helpful pre sales service and relatively easy to provide the relevant information required to facilitate the order. Unfortunately I was not able to get the faster charger due to a limiting switched supply for reduced amperage so to avoid major structural alteration accepted the slower charger. Web site said that payments were due after delivery but I was asked for money up front and they explained that the web site did not refer to services of fitting chargers. I requested that they change their website to clarify this confusion. On successful completion of the fitting of the lower charger, (Electrician arrived on time and was efficient and clearly explained the issues and operating) I realised that I had overpaid for the more expensive charger and was due a credit so emailed the company, but as yet I have not had a reply to my email. It seems that they fall over backwards to gain your order but are not as good in refunding overpayments. This has unfortunately caused me to reduce my overall good view of this company.
