Poor Service from Matrix

I thought I was the only one, but it seems like Matrix Customer Service doesn't exist. I looked at the reviews and for a Tracking Company, their service is pathetic. I have been trying to swop out four of my units to new cars, but i just can't get hold of them. It's been two months now and I am still stuck with paying for units in cars that I am no longer using.

It is refreshing to see , though, that their Debit Order system still works well, even though they do not supply the service they promise to provide.
