No show

I app**** online for a residential line to be moved after we moved to a bew house. No one contacted me so I phoned and app**** again. We received a sms stating that we should be available on 3 July for the installation. I phoned at around 2pm asking when they will arrive and the lady said they will come anytime between 7:30am and 16:00 and he is probably still on his way. I phoned again at 16:30 and then all of a sudden we didnt have a booking for that day and the system didnt show we were booked for the 3rd. Then she gave me a number for escalations because the manager already left. The number did not exist. We had to make arrangements and stay home for an entire day - for nothing.
