Bad customer service after installation

I will never ever refer someone to your company. The worst customer service I have ever received in my life. We have issues since late April, was told 101 excuses and that the panels are in the shade (which your technicians installed, in the shade on our flat roof, instead on the part of the roof that has sun throughout the day)so this would be expected, we hired someone to cut down the trees but still no difference. I officially logged a complaint on the 9th of May, a technician eventually came out on the 6th of June to check and said he would report back to your office, only on the 13th of June Waiden from Gosolr contacted me saying they are working on the problems and will get back to me asap. It is now the 21st of June and no one has bothered to get back to me or respond to my emails. We are totally off grid which we were when I app**** and also stated this, so currently costing us to run a generator every day to have a bit of electricity, in the meantime I am expected to pay my monthly installment but have no usage. For the last 2 weeks we have had sunshine and most days it charges to 16%, other days 0%. This needs to be sorted or you can come remove your system. Very unhappy customer.
