Cartrack trying to **** me

I had tracking device installed in my car in December 2020, a Panic button was also installed on the same day. But due to my car insurance I had to change my package - then the panic button was deactivated by the Technician. The Technician told me that all I need to do is to call their call center and ask them to reactivate the panic button... I did that many times But Cartrack keeps telling me to pay over R600 for them to re-activate the panic button. I do not understand WHY I have to pay for something that i already installed in my car? What is the point of me having a Panic button that is not working in my car? Isn't it better for Cartrack to come and remove their panic button?
