Terrible customer service

If been a costumer of cartrack for +- 10 years as I decided in January 2024 to upgrade my tracking device. Sins I started the process it is 4 weeks later and the new device has not yet been installed but they have already deducted the installation cost ! After numerous phone calls they every time have a excuse of they have send a email to the branch technicians to set up a date to come and install the unit which never happens.
