Mix Telematics

What is the big issue to cancel a contract. I canceled months ago but, rest assured every month like clockwork, a demand. I received a confirmation letter stating that its canceled and they are so sorry to see me leave ,by god, can the CEO of Telematix please throw a party and introduce the info jokers to the debtors clowns. I had my Beamy for years and no problems but by holy geez try and cancel , you're worse than the common cold, you just wont let go. With my new car I am forced to use their preferred supplier for a year. I am sorry but, I will not go back to Beamy. If you cant sort out your debtors department, I doubt your claims department will be any better.
