Paid for a service which i have not received. DONT USE CARTRACK!!!

Talk about absolutely **** service received!!!

Long story short i had a tracker in my car and at the end of the contract canceled the contract. My husband still had his tracker in his car, he sold his car and asked the tracker to put that tracker in my car. This was about 2 months ago. Tracker came spent 2 days trying to find the tracker that was in my car to remove it. THEY COULDN'T FIND IT!!! Eventually, on the 3rd attempt, they apparently found it. Then they forgot about reinstalling my husband's vehicle tracker. Keep in mind they debited my account R880 for the reinstallation which never happened. I called them to come to install the tracker seeing that they debited my account. They came out and installed the tracker. The best part this tracker has not been working. I paid two installments already and the tracker doesnt work. When i phone them they tell me there's a fault with the device and they need to reset it. Again I call them and ask them if they can test my tracker the guy said yes my ignition is switched off and my car is in Centurion, my ignition was on and my car was actually in Pretoria West. Now, this is concerning for me because it's supposed to work. I decided to reverse the debit order because this reinstallation is clearly not working, Cartrack changes the amount to R850 and debits my account again a day later of so i reversed the debit order again. A service call was logged 2 weeks ago and still nothing i have a device in my car that does not work. I should actually reverse the monthly payment as well for the last 3 months because this nonsense they put in my car is USELESS, TO SAY THE LEAST!! Cartrack you need to do better for your clients, you don't deserve this 1-star rating.
