Very poor customer service

I regret the first day I signed the contract with cartrack. The very first impression with them wasn't good at all. They struggled to fit the device in my car. It took them a week, they had to change from one technician to another to get it working. A few months down the line, the same new device stopped working. They wanted to charge me R600 to repair it claiming that it's already after 3 months since it was fitted. I was shocked. Since then I have had multiple problems with the same device and couldn't get good response. This company don't care about their customers. I have reported many times to customer service and also to the company CEO. It's shocking to see the CEO not acting. I have had many problems with their device malfunctioning. It's such a shame to know that I have only been with this company a few months ago and because they know that I am tied to a 3 year contract with them, they don't care. Recently, I was involved in an accident and my car was a writeoff, I have called them since to transfer the device to my new car. It is now more than a week, I haven't heard anything from them. I wrote to them again and to their manager I still haven't got any response, but they are still taking direct debit from my account even if i am not covered technically because my new car doesn't have the tracking device. Should anything happen to my car right now, I am not covered there's nothing they can do. I would like to advise anyone out there considering using this company to be very careful. Watch out!! Do your homework first.
