Cartrack Incompetence!!

I had Cartrack on my vehicle for over 4 years. I bought a new vehicle and cancelled Cartrack in June 2020 via Email and 3 times after that. I phoned them when they harrazzed me for payment and they said they do not accept email cancellation. I had to go through the unnecessary steps but did it on the 10th of December 2020. Today I receive another threatening email of final demand (hahaha) of R 637.00, which is 4 months premiums. I had enough of these *********** accounts department. I have cancelled several times via email, twice via telephone, I have a letter of cancellation from them and they still want to claim 4 months. I have sent a letter to the ombudsman as well as to my attorney. I now had enough of Cartrack I will also cancel my wife's Cartrack and also my other two vehicles. It's a pity I cannot urge all my friends family to cancel with Cartrack. I will put this on all social media platforms so all can see what happens with your account if you dare and cancel Cartrack!!!
