Is my reason good enough, Complain or not

I went on patient transport when discharged from hospital. I was due to be collected from the ward at 2pm so had arranged for a friend to be at my house at around 2.30. I was eventually collected at 7.15pm. I asked them why they were so late and was told that they were the night shift. They then told me that they had dropped off a 91 year old man in a dark and cold flat at 1.30 am the night before. There had been nobody to greet the patient and there was no food in the house. I considered myself lucky to be delivered home when I was!
