I was helped by the guy who works for this company to install my solar system on the 4th of November 2022. When I paid him we discussed that whenever I have problems hell come and help me. My Solar system stopped functioning on the 15 November 2022. I called the guy, for 2 weeks he didn't come, he demanded that I send him R1520 for transport from Johannesburg to Dannhauser by taxi, I refused to give him money as he had included it in the amount that I paid him. So today I saw in his whatsapp status, he had advertised the name of the company and his number was displayed in that post, I then decided to write a review since he has blocked me on his whatsapp. His name is PAISON JACKSON, HIS NUMBER IS ***, HE IS NOT TO BE TRUSTED. I AM WARNING OTHER CLIENTS SOTHAT THEY WON'T FALL FOR HIS TRAPS.
