TRACKER IS Nonsense, hell, blood suckers!!!!

Tracker was supposed to be a helper, but they are blood suckers!!! I hate the fact that i trusted this comany with my life. I sold the car in 2017, i went to them about the debits, and they told me that i have to pay the cancelation fee which they did not tell about at first. they went on debiting my account for a car which i no longer have, until i started reversing the money. They then took me to the debt collection (Blakes) company,where i was told that i need to pay R1200 for cancelation. I then made an arrangement for a contract cancelation, for them take it all at once. That was now on the 15 of July i paid everything, thinking the nightmare is over, guess what, today 31July 2019, they just sent me an e-mail, telling me that i owe, R0, 60 for invoice retrieval subscription, what, what the f.. k is this????? tjerrr!
