What do you think about me finally finding a complaint?
What did you file a complaint about?
I didn't like the way the receptionist bossed me around, she was making me feel like I was an idiot.
If she wasn't doing her job to your expectations, then it's good that you called her out on it.  Hopefully she'll shape up in the future!
Yes hopefully she will!
It's good to complain when someone is harrassing you or treating you poorly. This will help to make sure that the person does not repeat these behaviors in the future.
