PATHETIC GOSLR SERVICE

I have hired a gosalr system however, once you have signed up the service is beyond helpless and/or inefficient. I have tried on many occasions with queries and the call Centre or whoever takes your call tells you that the case has been escalated. It's been months and have never received a response. I get a call from Gosalr stating that they will make the solar system inefficient. unless I send them proof of insurance. this is after sending proof of insurance many times. I changed my email address (which is the same as user ID on the app) I cannot get into the system, and nobody seems to care as long as they get their subscription.... PLEASE CAN SOMEONE HELP?!
