Technical service, repair appointment.
Got 8 AM - 12 PM time window, no one showed up, and no communication.
I called the service, got another time window 3-3:30 PM.
No one showed up till 4 PM, and no communication.
I called back, and the answer is technician won't be there for several hours, at least until 7PM. Don't know when.
Is that how a technical repair appointment works?
