Poor service and technician not showing up for scheduled appointments

Disappointed is an understament when describing my feelings right now. I was scheduled fitment of the tracking device on the 2nd of January 2025, and technician was a no show. I called to find out and was told that the technician is in another town and will not be coming to honor the appointment and was re-scheduled for the 8th of January 2025, on the 07th of January 2025 I started receiving calls from the scheduling department and stating that the schedule for the 8th is not on the system they would like to offer me another date, I refused and demanded that the tech be deployed on the 8th as initially rescheduled. I was then given the 11th of January 2025 and still the technician was a no show, I called different departments the whole day yesterday (11 January) and I was sent from piller to post, my last call ended with a very rude guy telling me to call on Monday the 13th. This morning (12th January) I get another call from the scheduling department for a forth reschedule. What the hell!!!!
