Poor service delivery

Worst service I experienced in a long time. I had a fully off-grid Studer system to the value of R450k. The system was installed 5 years ago. After lightning damage, I had an insurance claim and approached Red-energy International (Johan Pieterse) to assist with a new system. After expressing specifically to be off-grid again, he quoted on a SunSync system without assessing the capabilities of the Studer's deep cycle batteries. Paid deposit on 28 April 2022. Installation was done only on 11 May 2022. On 14 June 2022, I had to pay another R75K for a third battery as the two they quoted on, was not enough (No testing of the house's energy consumption was done before quoting on the SunSync system). The system never charges the batteries more than 60% when the basics are used during the day. We are unable to use our underfloor heating and aircons. One day of cloudiness and the system does not charge more than 25%. Regularly between 05h and 09h the batteries' alarms go off as they discharge below 20%. The only answer I got from Johan is that we will not get more from our existing ×30 (310W) panels. No service has been rendered after the installation of the third battery. I made it clear in numerous emails to him and Eon that I want a refund and for them to remove the system as it never met my requirements for an off-grid system. After numerous requests, Johan stated in an email that he will refund the money after subtracting almost R18K for installation and handling fees. It has been more than 2 weeks and the money still is not refunded. Johan does not answer my calls or reply on my whatsapps. I have already been to my attorneys to assist me. No success. This is not the type of service I have in mind after being quoted R345 000 for a system that "works" like this. I will never refer any possible clients to red Energy International. On the contrary!
