Fitment and schedules .

I signed up and registered my car for a tracker, i gave them a time and date for my car to have the tracker fitted, they never showed nor communicated with me as to why they never pitched, i had to call again and waited almost 20 mins to get help, then i rescheduled my fitment, and on the day the technician flagged my request and my time i said for it to be fitted, they ignored and closed the job card, again no communication whatsoever, i then spoke to them again and again waited almost 20 mins and wasted my airtime, only for them to reschedule again, and it was always a inconvenience for me as i planned ahead to their time but they never pitched and wanted to reschedule again .
