Netstar the Worst Tracking Company ever

I have had a Netstar Tracking device installed in my BMW in 2016. Since then I have had nightmares with my car. Their tracking device was faulty. I have been calling Netstar to come a d check their device, however when the Technician checks, I was told everything is fine. I have changed my car batteries three times. However I was still having the same problem. On July the 24th, 2019. I decided to cancel my contract with Netstar. Because I was introduced by my Insurance Dial Direct, I called Dial Direct to assist with the cancellation. I was transferred to a Netstar Consultant. Who I specifically asked if there would be any outstanding amoun that I needed to pay. She said no because my contract had expired already and there is no outstanding fee that I needed to pay. I also asked her if they can come and remove their device from my vehicle. She said they cannot as the device belongs to me, the only thing that they are going to do is deactivate the device from their system.

In August 2019, Netstar did not debit my bank account. In September 2019, my bank account was debited with an amount of R296.00 which I instructed the bank to reverse. Two days later I received an SMS from Nestar informing me that my care was jammed while my car was parked in my garage. Few minutes later I received a call from Netstar Consultant asking me if I am okay because they have received a jamming alert. My question was why isn't my device deactivated as per my request on the 24th of July 2019! And why are they giving me false alert information whereas my car was parked safely in my garage! The Consultant said she was not aware of that. Exactly 2 minutes later, I received a call for person who told me that he is a Supervisor of the Consultant who just called me to inform me about the alert. He then said my cancellation was not completed. I asked him why was my cancellation not completed on the very same day I asks for it to be cancelled. He said he doesn't know why but that's the finance department issue. I told him that I don't want anything to do with Netstar as they are ***********. Then I hung up. Later on that very same day someone from Netstar called and said she would assist with completing my cancellation. But then she said I must pay the outstanding amount if R296. I asked her what was is for because when I called the contract I asked if there is any outstanding fee. I was told there wasn't any. I asked if they can take out their device, I was told that they can't. Now I'm getting calls from Netstar demanding the outstanding amount which by the way I refuse to pay because if they had trained their staff to know about the requirements needed for cancellation. We wouldn't be here. I hate how Netstar operates. They don't care about their Customers. All they care about is the money. I wouldn't recommend Netstar to anyone. They have the worst service ever
