I am absolutely frustrated. I had to take time off...

I am absolutely frustrated. I had to take time off of work to bring my son to a medical appointment. Now before you go thinking this sounds like I am a bad parent...what is wrong with the situation here? I leave work at 1:30...for a 3pm appointment....at 4:05....there is no doctor or nurse in sight. When mentioned to the receptionist, she claims that she is confused and she wants me to wait so she can find out what happened....an hour and 5 minutes after the fact is a little late for that....I can't even give this one star!! And my poor son is having significant issues so I wanted to follow up with the person who knew his history best..rather than having to start over...now it looks like I will not have a choice...If a doctor is running late....you're on my time and I pay your bills....it would be courteous and polite to tell me there is a delay and give me the option to reschedule...not make he and I wait for an hour and 5 minutes and play dumb and confused...and decide you want to fix the situation because I called you out on it.....one star is an overstatement for a department that is known for overbooking their doctors to try and keep the patients happy....I'll be looking elsewhere. I can't afford to have my time wasted.
