MATRIX Vehicle tracking. Appalling Customer Service

Well where to begin, I have been a Matrix client for 12 Years, MX3 Trackers in all my vehicles over that time. I recently sold 2 of my vehicles and bought a 2 new ones, I informed Matrix with a full 30 days notice that this was happening, and to cancel the subscriptions which were month to month. No-one rep**** or made contact (other than the automated "your query has been recieved" email response). All fine and well, the Old vehicles go, I take delivery of the new vehicles, and again email customer care informing them that I now no longer have the other 2 vehicles, the months notice is up, but they are still active in my app, being tracked without the new owners permission, (about which he wasn't happy I might add). Then Someone from Matrix suddenly rings me, and says the "Contract" isn't up until the end of April, which is complete nonsense as I have had the trackers in the other 2 vehicles for over 3 years, and that was an extension of using MX3 trackers for 10 years before that. Not to be deterred they still debit their Payment at the end of March, and continue to keep the tracking active on the vehicles which I no longer own. Nary a question as to whether I might want install their product in my new vehicles. So I have now gone to Tracker. Matrix have lost a client of 12 years through a "couldn't care less" attitude to customer service, all they wanted was their R485.00 for April, well they got that and lost a lot of future revenue. I hope it was worth it to them, Que Sera Sera :-)
