No installation and no feedback

Hi <br> An appointment was set up for Friday to install a new device. No one pitched and when I called the call centre I was promised feedback yet up until today I received none.<br> <br> I called the fitment centre and their response was that they couldn't get hold of me the day before to find out if they must still come. What a load of bull. An sms was sent to me stating that should I wish to cancel the appointment I must call, so surely I would've called had i wanted to cancel. So this just doesn't make sense at all. I would at least then have expected the fitment centre to provide Tracker with this feedback so that when I called them then they would've at least been in the loop as to what was happening.<br> <br> Very bad service considering the fact that I waited and even cancelled an appointment. Makes one think that if this is the service I'm receiving now, imagine what I will receive in an emergency.<br>
