Money hungry company

Do not take a tracking unit from Cartrack. I had 2 devices, sold both cars. Cartrack refused to cancel and wanted me to pay R3000 to move one of the units to a new car. Tried cancelling in 2021, it is now 2023 still paying for cars which I no longer have. I decided stop the payments, now the lawyers letters are coming. So this is a 1 way relationship. Just pay that's the aim.
