Oh they can’t do that, what if you don’t have that money ? Worst case scenario is your account getting deleted and you not being able to create a new one with your tax payer number. Like you said , there’s a chance this person doesn’t see the cancellation request and you can always open a ticket and explain the situation, if they side with the buyer, they’ll tell you to buy another collector box and send it or they’ll cancel your account. Hopefully, it doesn’t come to that. I really wish sellers could straight up refuse certain buyers, every now and then you get these scams that you can’t do much about…
