Poor service

I already wrote a review on Cartrack for excessive charges. However, I am now being harassed for payment, but the work/service is not completed. I booked a de/re installation on 20 May 2026. Nothing happened so far except daily calls and e-mails for payment. I inform their accounts department that they can deduct any time after the job is completed. Priority is sucking money out of me regardless of whether the job is completed. Very poor. Stay away.
