No CoC , NO after service

What you do , do not use them. The installation was perfect but no after service , no CoC making IT UNINSURABLE. They installed the system while we did not have power from Eskom and to date i cant go to the Grid. The system does not allow me to go to the grid. I have called a million times with no answer and finally last week they picked the phone and said they will call on Friday but nothing. If there is no sun we stay in the Dark thanks to Phase Energy
