MEA Piano Studio

I checked out the website and the music teacher here sounds very qualified. I see that she offers 30, 45, and 1 hour lessons. Since I’m a beginner, I signed up for a trial lesson for 30 minutes.
The music teacher emailed me and notified me that for adults she ONLY offers 60 minute lessons. I said I wasn’t interested in 1-​hour lessons since that’s too long a lesson for a beginner and asked why I can’t have a shorter lesson to start with. She said that «1 hour lessons work best for adults» and asked if I want to cancel my appointment. I said if you can’t be flexible then I’ll go ahead and cancel.
I tried several times to talk to her by phone and left 3 messages but she never returned my calls.
She sounds well qualified, but who wants to pay for private lessons with someone who’s so stubborn, inflexible, and doesn’t bother to return messages? I can find another piano teacher.
