Krap Gosolr and Sparky installers

This must have been the worst idea my partner and I have ever made we have barely been with Gosolr for a year and have gone through 3 8klw inverters I don't know who is more useless Gosolr or Sparky installers we have had non stop issues.We are still wating for a manager from Gosolar to come and see us (6 months waiting) after countless phone calls and messages not a peep Sparky installers have come out multiple times and they can't seem to find any problem but going through 3 inverters Sir we can't find a problem it must be user error how would it be a user error if they can't even see that a earth leakage that they installed burnt out and I quote the electrician ( Sparkys electrician) sed no the skrews are just loos after trying an hour to titen them to he eventually rep**** it as well as we had a 2 site inspections one from a lady that I can't remember who found that the installation was not up to standerd and Sparky had to do the whole installation from scratch we also had Marius and Profecer from Sparky a did a site inspection and still found problems and non of them have been seen to and they made a list but that list went missing and nothing happend . I also had to replace 2 tyers on my car because when they put more panels on my roof they left the roof *****s all over my driveway. And they also did not even mount my inverter on my wall properly it was held up by 2 *****s and so lose it almost fell on my partners mom. They aslo broke the tamper proof seal on day of installation and sed no it was us who broke the seal.
