Late bus

I am writing a review on behalf of my grandmother. My grandmother was supposed to catch the bus last night and the bus was 3 hours late. Messages went out to some customers, but my grandmother did not receive a message. She is 77 years old and had to wait next to the road at night. My grandfather is 83 and had to wait with her. It is really dangerous and they are vulnerable. This is really bad service and unacceptable.
