Caprica Solar Randburg - Shocking service

Absolutely shocking service. Inverter was fixed and installed, and they received payment over a month ago. The inverter did not work, and numerous appointments were made, but the technician never pitched up nor did they have the decency to advise that they are not coming or why. Last week the inverter caused us to not be able to use the toaster, microwave, hairdryer ect and I had to purchase a heavy-duty extension to enable me to get electricity from a neighbour. I called the company and i was advised that they will come out on Friday, then Friday became Monday (and obviously no one came) and now on Tuesday I get told they don't have vehicles available, and the manager is missing in action?? Can the manager not use his personal car to bring the technician here? I have asked for the manager to call me, and surprise this has not happened. Wish i could get the service that other people have received.
