I think this one is on you and it is a $200 lesson. You might be able to get your money back if you make dealing with your less of a hasel/cheaper than refunding your $200 but do you really want to become one of those people who finds a way to weasel their way out of their own mistakes instead of learning from them? It does not hurt to just ask, tell them that you made an faulty assumption and they might give you back some or all of your money but don't try and make it out to be their fault or it may very well become a habit in life.
