Terrible after sales service

We signed up for the larger unit for single phase, initial start was marginally bumpy but the installation went fine and the system works well. And that was where the service stopped. It took 3 weeks and many emails and phone calls to get the insurance letter. It has now been 4 weeks and we do not have Certificate of Compliance. Good luck talking to anyone with authority at Gosolr, they leave the juniors on the frontline and no one takes responsibility. The directors are all industry bigshots but I doubt they realise what a **** name they are getting. Hint: Don't let the installer out the drive way unless you have absolutely everything, because no one will help you later.
