Have a system that is a white elephant as its not working.

My system is not working since I had to fight for my installation to be completed. Firstly, I had to fight to get your electrical partners to come and finish my installation. Now since my system is supposedly up and running my solar panels per day only put out an amount of 13,00W which is not anywhere near what one 450w solar panel is meant to produce, and I have 8 panels. My two batteries don't charge to a full 100% either. I have called the call center several times for one person to change settings and then another person to change settings and boom Wednesday evening my system shut down during loadshedding. Two tickets have been logged with your electrical partner Nano-Electrical and nothing. I was assured by someone at Nano-Electrical that they would send someone out to come and have a look yesterday or this morning as they think it is a connection issue. No one has pitched up at my door and I am actually sitting with a white elephant in my house that is not severing the purpose of what I actually got it for. This is ridiculous service from you and your partners. I have fought since installation to get a working system, and no one is hearing my concerns or feeling my frustration. Gosolr imagine this was you sitting on the other end. I want this fixed I want a working system as promised on your website!!!!!!!!!!
