Matrix beyond unprofessional

I contacted Matrix before I traded my vehicle and procured a new vehicle to ask how it works with transferring my existing tracker from my old vehicle to the new one. The consultant advised me that they do not transfer the tracker and that I need to install a new tracker on the newly procured vehicle and that the old one will be cancelled automatically. This has not happened and still shows on my invoice and I still have to pay for a tracker that I no longer have the vehicle to. Tried phoning Matrix and holding for an hour to no avail. I've sent multiple emails and nothing. **** poor service to say the least. I will now be forced to cancel the debit order and venture to use one of their competitors for service it seems.
