Be warned: Everything about Cartrack is terrible

For many months my car battery was being inexplicably drained. The Mercedes mechanics AND Battery Centre suggested that it was the Cartrack devise. (It was.) I canceled the service, at which time they told me that I would I have to pay for an extra month's service. I agreed and TWO more months of service were paid for by auto debit - the month of service, plus another month of service. I drove to Cartrack in Bellville to have the device removed. It took three hours while I waited. ALSO, while waiting I noticed a young man driving my car!! I had not given permission to anyone to drive my car - AND he was driving my car while NOT wearing a masking or taking any other safety precautions. What gives him that right? After three hours, they finished with my car. The place on the vehicle where they install the device is supposed to be a secret - but there was black adhesive smeared all over the exterior of front right fender of my car and there was damage to the inside area of the right front headlamp. The rubber seals had been pulled away and damaged. Black grease and melted rubber adhesive smeared all over the front of a white car. Whatever. At least me sad relationship with Cartrack is now over and my car battery will no longer be drained by their devise. WRONG. Now I get multiple phone calls each and every day from Cartrack (sometimes they just call and put the phone down) telling me that I owe them another R120 for an additional month. I had already paid for more than an extra month from the date I canceled. The payment had been paid by auto debit for years and years - including the extra penalty month. I'm not paying them for a second penalty month. I thought I had heard the last from this miserable organization. But NO. They will haunt you forever. BE WARNED - If you read all these reviews, 1.5 on Hellopeter (it SHOULD be less than 1.0 actually) and you still chose to sign up with Cartrack you have only yourself to blame.
