Worst Service & Company I have ever used!!!

This is BY FAR THE WORST COMPANY that I have had to work with. I never signed a contract, I was on a month-to-month with them. I sold my car a year ago already and they still phone me every single day claiming that I owe them money, they still try to debit my account every month and this all after I cancelled the service right after I sold my car. They gave me over to Viljoen Attorneys (who also phones me every single day claiming that I signed a 3 year contract - I'm still waiting for proof) and yet they still claim my account is NOT CANCELLED LIKE I TOLD THEM TO DO A YEAR AGO & THEY ARE STILL CHARGING ME MONTHLY COSTS!!! I am usually the nicest person to consultants, but neither of these companies can even make a note that someone already phone me that same day - This is absolutely pathetic!!! I am so disgusted with this company, don't ever use them!!! And, Cartrack, don't even bother with your pathetic apology that you copy & paste to every bad review - use your resources to solve problems and to stop your extremely rude employees from HARASSING me EVERY. SINGLE. DAY!!!
