"Left waiting for over an hour without any…"

I had an appointment today at 13.10 I arrived at 12.30pm for my appointment in good time. I quickly noticed lots of people going in before me which is fine so I decided after an hour wait from my appointment time booked to ask why I’ve not gone in and was told they couldn’t give me a time and were running late. I informed them they should have put the lateness on their whiteboard for people to see how late they were running. I couldn’t stay any longer and have had cancer so will no doubt have to wait ages to get in again I’m not happy
