Wonderful advice by @larryz here, if his tip doesn't work - I'd strongly recommend not trying to do anything else suspicious with 3rd party sites or anything and just contact customer support/help desk, they will definitely help with your issue.
Yeah, I'm very impressed as well. I mean they are top of the top but still, super excited to try when it opens up and I hope it's done by 2021 too since it's the year I plan to visit again!
