1st flight lesson - NOT

Would you believe I was stood up by my first flight instructor? I arrived 10 minutes early for my 1st flight lesson that was scheduled last week with the Chief Flight Instructor, and was told I didn't have an appointment listed. Here I am, a 57 year old, mature professional, willing to pay thousands to this company to train me to fly, and  I get stood up! WTF? Is this any way to run a railroad? I'm still awaiting an explanation 4 hours later. Man, what a bitter taste in my mouth. This is a heck of a way to start a long-term business relationship.
