Thank-you for the comments.

I let my teacher know that I appreciated her extra time and in the future we'll do better to make sure it stays to our scheduled lesson length.

I'm afraid you can't do that. Since you mentioned it, Why don't you send a message to him/her and say something nice instead? 

You could also arrange another lesson with that teacher. It's an option and it's up to you.

could you contact them and ask for their credit card number or paypal account? 

you could book a lesson and never show up. They earn free money and relax.
