I love how some people use words like, 'unacceptable'. What alternative is there to accepting what is? I know of no way that anyone can change what is to what they wish was. LOL
I read this as a tempest in a teapot. You are flying public transportation, it's a bus with wings. Your expectations as to what level of service, professionalism, DYKWIA acknowledgement, etc. should be in line with that. 'Incompetence or lies', no, just a standard foul-up that happens every day to someone, somewhere. Today was your turn that's all.
