Terrible Customer Service, Tracker App no longer working

Absolute Joke of a Customer Service Department.

Firstly I picked up that over a month ago the app hasn't been able to detect where my vehicle is. I have continued to test this each day and it hasn't updated at all. Could have been longer but I only picked it up a month ago.

I then try and contact Matrix, firstly there is no number to phone. Only a mail address.

I emailed this address and what was I expecting, as I have had zero response back. I have requested to cancel my contract and still no response. Yet I get called to be offered other contracts?!

All I want to do is cancel this contract considering it's not able to locate my vehicle.

Reiterate, no way of contacting the company at all. Only through a mail web service.
