Go Solr Installation unsafe and non compliant, huge safe risk

Attention all. Please get another qualified electrician to check Go Solr installation. I have the system installation checked and there were several non compliance against SANS and COC which could have caused a serious incident like Fire or electrocution. I am struggling now for 2 weeks to communicate with the non competent staff of Go Solr. I told them numerous times to come and disconnect the system from my DB in order to be safe and remove the whole system. They came and disconnect from DB and again I am fighting again with them to give me a Coc ar a official letter to state the disconnection was done and left safely. Now they are ignoring me. Is this how a business treat there customers. Very very bad service. Quickly to take money but poor to communication and to fix the problems. Also half way thru the rent 6 months, a quality check was done and the person informed me that one batt is not connected properly and was not being used and they fixed it. I made a query on this, which later the person indicated that he never said that and I am lying. Which made me more frustrated.
