Beware of wisolar, installation and not honoring their warranties

I had an initial wisolar installation...costing me R 170 000...all was relatively ok...

Then I decided to upgrade the system this year...again asked them to access/advise and upgrade with additional panels and additional batteries...costing me another R 100 000

The installation was done...but there were issues right from the outset. These were raised and are now being ignored.

The system not performing as said it will be, based on the additional panels and batteries installed.

I just want my stuff to work.
