Bad advice and service

I contacted them for assessment and quote to install inverter, battery & solar panels. An assessment was done and advice was that 5Kw and one battery would be more than sufficient for my usage with geyser and oven added. The first sign of loadshedding, the battery wasnt lasting, so the geyser and oven were removed. I then wanted the inverter app added to my phone so I could monitor it and they didnt know how to do it. It took months before it was finally sorted between a diesel supplier "friend" and the supplier of the inverter - not even All Energy were involved. Then the battery died again! 0% dead!! I asked for it to be set that it didnt drop to 0% as they needed to collect it and take it for a recharge at the supplier. Of course, I was charged for the collection AND re-charge. This was March 2024. We haven't had much loadshedding since until recently, we had an outage for 24hrs and the battery died again. This after they assured me that they had set it to switch off at 20%. They collected and took it for recharge and they had the audacity to send me an account which I politely refused to pay as it was their settings that was wrong. They responded that the next time (how confident are they that it will happen again) I must find another service provider!!! I have no problem with their installation. They brought in an independant electrician to check and sign of the COC BUT as for the rest of their knowlege of how the products actually work - they have NO clue!!! Their client service also has much to be desired!!! I'm still waiting for the proof that the Solar is registered with Eskom, which they assured me in July 2023, they had app**** and Eskom had a backlog.
