The worst customer service for fitment

I am so unhappy with how my father was treated today. I had asked the Cartrack scheduler if I could get a fitter to come out next week or after, but he said that there was availability today at 3pm at your Oakdale branch. So I took it. When my father was there and waiting for 2 hours, they kept locking up the sections he was sitting in, asking him to move when eventually they locked the whole place and waiting for the vehicle, to the point where he had to stand outside in the heat and wait! My father is 70 years old - is that the right way to treat customers? I understand your workers wanted to go home as it’s the day before Christmas but then why book an appointment that takes 2 hours at 3pm? I’m in two minds about your product now and I’ve just joined.
