VERY VERY BAD SERVICE FROM MATRIX, BEAME, POWERFLEET

We were on a month to month service with Matrix after out Contract of 3 years expired. In Feb this year I noticed that my device stopped working in Dec 2023, and I phoned Matrix to report it. I was then told that I need to take out another 3-year contract with them. (By signing the new contract, they will then replace my device.) I refused the offer and then asked them to cancel my agreement. They gave me a reference number for this. In the meantime they keep on deducting money from my account. I have spent many hours with them on the phone, but they are not honoring my request.
