Tracking device causing problems

I had the Netstar tracker in my car since the 12 July 2024, and it is already faulty. And because of it being faulty it drained my car’s battery to such an extent whereby I need to jumpstart the car every time I want to start the car to drive it. I tried cancelling my contract by them yesterday, and a highly arrogant employee kept on telling me that they will replace the tracker so I will save money as they won’t charge me for it, and the more I said that I want the tracker out because I already have plus minus R2000 damage on my car because of it the more he insists on replacing the tracker. Finally the guy approved the cancellation but I still have no received a call from netstar to take the tracker out so that I can actually replace my battery and know that it will be safe in my car. They also take from 3 minutes up to respond to panics buttons that are pressed, and by that time one could be dead. And to put the cherry on the cake, I must pay about R300 cancellation fee even though the tracker is not my fault. They should really work on improving their systems especially when it comes to ensuring that their systems are installed properly and that they don’t drain the battery.
