Cancelation

After countless emails and phone calls over a 6 month period to cancel my Cartrack subscription Cartrack wants to charge me R1700 cancelation fee for a device that was installed and after a 3 days still could not use the tracker hence I cancelled after 3 days due to poor service and got another company that had me up and running within 24hours (and cheaper). Cartrack could never get back to me after countless promises to phone me back to sort out the problem, Cartrack will rather send a SMS to inform me that I will be handed over to debt collectors if I do not pay. Tired of Catrack's incompetency, poor service and threats.
