Bad service and wrong system installed by Gosolr

I was called by the Sales team at Gosolr to sign up with the company. I asked a few questions on this system works and then emailed the questions as I needed proof of what power I would be supp**** and the appliances and other unit in my home this would cover. When the installers were busy installing I was excited and had told them what the sales team had told me the system would manage and when the system was just about installed I was told by the technician this system will definitely not be covering half the appliances I was told would be covered. I then emailed Gosolr the sales team who I was dealing with and he told me to sort it out with support, He got me signed up and despite signing me up under false pretenses and false information give just to get a sale he did not fix his errors which are recorded on email. The calls are recorded Gosolr can go back on the phone calls and email correspondence.. I then recently found out the technicians had left half the house off the solar and wondered why when there was load shedding this part of the house did not function. They eventually came of to rectify and yet again noted my garage and geyser were left off as well even tho I was told this system would cover my geyser, aircons and all plugs in. I yet again emailed and have had no response. When I asked why the solar is only running at 2.4KW even though there was a 5KW system installed I was told the panels cannot run at 5KW. Gosolr sign a customer up promising the world and after installation leave you hanging. I have all the email correspondence and Gosolr have the telephonic conversations that took place. I had an electrician look from the outside and he said just by looking a how the wiring was done this was a terrible job. I still have not received a COC certificate. Gosolr need to upgrade the system to take the load I was promised I would get. I am not bound into the contract due to the manner of the sign up.
