NESTAR DEVICE NIGHTMARE

CAS ***-G6F7 my netstar nightmarae!!!!!!!!!!!!!!!!!

i bought a car and my car track account was included in my finance deal. now i have changed the car and requested Netstar to remove the device to my car. they have done that but the device is still showing the oldcars location with the new registration.i have contacted the Nestar company which told me the device will be updated in 24 hours. the car is new and bank financed, the insurer requested that i send them the installation certificate. to date nothing is working i even pressed the panic and month end i must still pay them R660.00 for the ****ed up bush job they did on my car.
