Cartrack a disappointment

Hi all, Extremely disappointed at Cartrack, I registered for a tracking device in 2020 after getting a new ford Ranger then once financial get worse I told them to migrate that device to my old NP 200 Nissan since I’am returning the car. Now almost 2 years later I still pay for that device , install on that Ford Ranger that I don’t have anymore. Although I paid for that deinstallation, I was blacklisted by them after spending 10 month overseas, been obligated to pay off what I owe, and the blacklisted amount and still for the monthly instalment and nothing till now happen no device on my old NP 200. For a monthly of R180, blacklisted fees of R1800 and the settlement fees of close to R1500 this company is not to be trusted Period!
