Absolutely. And it looks like they will be doing it shortly, so I don't see a problem with it. Your customers are not facing any more downside than you are, they preordered and changed their mind, they can wait some time before getting their money back independently of time being money due to their gambling addiction. I wait a couple of months all the time for my own refunds. I sometimes even process refunds and never had anyone complaining if it wasn't done right away because of time being money. They were just happy they got their money back. Some of those refunds had been sitting on a shelf for a good couple of months before I got to them, same story as here, I was busy with more important things.
Also, I'm assuming we are talking about 3 weeks here, two months would be getting a bit much. I honestly have no idea.
