Poor service from Cartrack

Extremely negative experience and poor service with Cartrack. Recently I traded my old vehicle in and purchased another vehicle, tracking system had to be removed and refitted, requested transfer for tracking device and made payment. Explained to Cartrack urgency as dealership wanted to sell my old vehicle. After I called Cartrack again to get the device removed, they informed me that they dont have technicians available. Cartrack then told me I must pay additional fee to fit new device as I still had months left on my subscription. I then had enough of the poor service and requested cancellation of subscription. Again they demanded another fee, which I paid via EFT. One day after the payment was made, I received a message threatening me with legal action for the cancellation fee, after I sent the proof of payment. They then charged me for another month of subscription and again legal threats. I paid the last subscription via EFT and Cartrack also debited my account for the subscription fee, after cancellation. I made numerous requests, yet still no refund from Cartrack for the subscription payment done via EFT. Needless to say I will not deal with Cartrack again and really not recommended. The arrogance and dont care attitude is not how business should be conducted.
