WHS Solar Group - stay away

I ordered an inverter and lithium battery first. Inverter were new, although not product as on adverti*****t, battery arrived later, looks refurbished/second hand. Spray over *****s and chipped paint. Unfortunately based on inverter and quick delivery, I ordered solar panels before battery arrived. Had to pay Courier Guy more than R800, as size specifications were given wrong by WHS Solar. They asked me to pay and I will be refunded the next day when their finance lady is on duty. Still waiting. Solar panels delivered differ from what I ordered, made in China..no response. Ordered tracks and brackets for corrugated roof, received for tile roof. No address to visit. No feedback.
