Unprofessional Customer Service

I am so disappointed with Car Track customer service. They have scheduled for De-Re Installation, I took a leave specifically for it no one bothered to contact me for time, even when I did and given time no one pitched up. And I was told a lie about tyre burst and technician will be at my place around at 17:00, no one came, when I contacted them again I was told that Scheduling Department is closed, my appointment was rescheduled for the next day, how? when I was not contacted, and had a journey to travel on the day. If it was me who was not available on the scheduled date I was going to get a fine, how then do we handle it when this is from their side, waste of my leave day at work, my entire day waiting for them, costing my journey to EC. No one contacted me to even give a way forward for this next day reschedule
