Useless R40k backup system

We bought an inverter and battery from them before moving down to the coast because we wanted to be sure we'd get service if something went wrong in the future since the system is quite expensive (more than R40k).

After spending all the money on having the system installed in the new home we found that the inverter is faulty. A brand new unit that I transported in my OWN vehicle to ensure that it wasn't damaged is faulty out of the box. Unable to get hold of them telephonically and having to communicate via email where it takes 2 days to get any kind of response from them they advised us we need to log a return. Logged a return and DAYS later no pickup yet. Then we still need to wait for them to send the unit in to the supplier which judging by how long the process has taken thus far will be 7 - 14 business days, then another 7-14 business days for the supplier to get back to them and then depending on the outcome probably another 7days to get the unit here.

I won't recommend GeeWiz and definitely won't be supporting them in the future. I've gotten great service from them in the past but it looks like they're unable to support their customers.
