Unfortunately, it is exactly so. In some/many cases, Wise freezes (especially business) accounts without an understandable background but this case is perfectly transparent. (WTF, how could you pick up an idea to pay for a
crypto from Wise – if it is perfectly clear that it leads to the account closure? But it is your business
)
If your priority was and is to have your money back ASAP, it was probably contra-productive to file an appeal. The probability to have your account reactivated is extremely low and the appeal process only eats time. (AFAIK, they will not send you the money back until closing the appeal file.) Perhaps you can write to them that you understand that you made a mistake, so you are withdrawing an appeal and just asking for your money back (a small “sorry” could also help).
At this moment, there is no base for complaint against Wise with the Financial Ombudsman. You can use it when the process takes more time than it is in ToS (or more, than it is reasonable).
