Terrible service

I has a tracking unit fitted last Thursday, used the vehicle later that day and realised the tracking was not working. Called the customer care number and reported it. Was told that someone will call me to schedule an appointment. No-one has called. I escalated to the CEO (at CEOescalations), surprise surprise, no response. Now they want to sell me insurance. They called me several times to make the sale, but once they have your money, doesn't seem they care.
