Lessons were paid for in cash, no receipt. I have actually had several sets of lessons, usually from the mother or an associate, but not normally the daughter. Lessons from the mother and the associate were fine, but the lessons from the daughter were half-hearted at best and I had told the mother on previous occasions that I was not pleased. Her daughter apparently believes that if I just tried harder, I could undo built up scar tissue from a decades old back injury which prevents me from moving very quickly and which makes riding over jumps rather unpleasant during extremely cold weather. The daughter insisted on having me attempt jumps during the lesson, even though I had that very morning pointed out that I would be loathe to do any jumping that day. As a relative beginner, it's fairly easy to change the focus of the lesson (which is what the mother always does), but it seemed that the daughter felt that I just wasn't trying hard enough and after a great deal of rolling of eyes and exasperated sighs, she left. I obviously didn't communicate to the mother as well as I thought since she had her daughter teach the last lesson. One last thing, the daughter much prefers to teach children how to jump, and has little to no empathy for me as a much older student who simply wants to learn how to safely ride a horse and is willing to spend a lot of time working on the basics of flatwork. Jumping is not my main focus, and I have discussed that several times with the mother and the associate.
I have e-mail communication acknowledging receipt of the money, but nothing in writing that says PRE-PAID lessons which have not yet been taught are non-refundable until the last e-mail.
I will take the suggestion that I communicate with the mother that I would be willing to take the lessons with her only, but no one else.
