POOR SERVICE DELIVERY- WASTE OF MONEY AND EFFORT

My premium is more than the system that was/is installed. Their agents have been saying they are gonna come and fix it. It's been months of me paying extra for nothing, all their agents are good at is asking for an address when I raise this with them. It's funny how they won't even refund my money all these months, since I have been actively trying to fix this issue with them. Also, the number for Coastal does not even go through, which means I am paying money to a company that can not even be reached telephonically. WHAT A WASTE OF MONEY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
