Coretech Group\Richard disappointment

I am having a very difficult time with Coretech group and Richard. I paid R132000 to them in the beginning of August 2024 for a solar setup. As at today date which is 2024-10-17 I am still missing my 12kva Deye Inverter and a battery etc. so effectively the system is useless. I have given them numerous deadlines and all of them have been missed and all promises broken. Richard constantly says that he will deliver stock and finish my system but never does. Definitely an experience that I would not wish on anyone
