I'm as curious with the others about if you contacted the trainer. I don't know any trainer who chases up a student for a lesson, if you want to learn that's your responsibility.
At the risk of getting "shot down" I'm also going to say that I'm a bit suprised that you couldn't be bothered to spend a bit of one on one time with your horse. In my opinion, having a horse isn't just about riding, it's about becoming a better horse(wo)man. I spend more time on the ground than I do on Bandit's back. As a kid/teen I would spend hours on end with whatever horse I was riding at the time just grooming, chatting and getting to know them. If I were after driving out to the yard, and couldn't ride I wouldn't just turn around, I'd get off my backside and do a bit of ground work with the horse.
Stop for a minute, open your mind, learn. You may not agree with what I say, I may not agree with what you say but we will both learn something new.
