Bad bad bad service

I am writing here in the hopes some one can help me. I am frustrated beyond words. We have a system with God Solr and have been happy and recommended to many people in our complex. This was until I had an issue with the battery not working last Friday. I called them and explained system had gone down and had to reset the system etx. Inverter keeps saying no battery.. On Monday we had a huge eskom outage and our system did not kick due to to no battery. On Tuesday they came out and said the battery needs to be replaced and faulty. The technicians stood in my garage and said it would be done the next day. Wednesday nothing and no power not even off the panels. I was phoned on Wed afternoon 3 times to tell me that the guys are outside and waiting. Went outside no one there only to be told the went to the wrong hosue and confused me with another customer. We'd afternoon I was told they would be here on Thursday to do they had confirmed this. Sat at home waiting as they can not give a time or anything. At 3h30 I called again and I was told they don't know where I got my information from but it won't be Thursday after waiting a full day. At 16h30 I spoke to another person to find out what is happening and then get told they trying to find stock of my battery. So from they outside my hosue.. To Thursday definetly to no battery now but can't gice me a time or date.. It has been now 4 days with no power and GoSolr doesn't get back to people at all or can give information. Can someone sort this out, or at least give feedback... I used to sing your praises and now I regret doing that as this has become beyond a joke.. The left doesn't know what the right is doing and no one gets back to us
