A company I was involved with had a business account with Wise (Transferwise). One day out of the blue they froze our account and said only withdrawals from now on. The "reason" they provided was Violation of Acceptable Use Policy. They wouldn't even say which clause or give any details whatsoever. When asked for review we got an reply that after extensive review they can't reinstate the account, the decision is final. During the whole process it was painfully clear that they didn't read our messages or even try to understand the situation. After a few weeks and many emails with supporting evidence that we really can't see how we broke any of the terms the account was reinstated - a surprise to us. It seems like eventuall someone actually did take a look at the issue. But we never heard why it was frozen in the first place or what made them reinstate it. We probably just got really lucky. During that time we couldn't do payroll. We couldn't collect customer payments. It could have killed us did we not quickly scramble to get an alternative setup.
The common theme is that a company makes ill-advised banning decisions that have a big impact on a single user and then appeals are not treated seriously. This can have devastating effects. Usually this happens after the company who is running the platform grows to a certain size where they don't need to care about a low percentage of users anymore and rather save on support staff costs. And to add insult to injury they lie in your face about having conducted "extensive" reviews and having "carefully" decided all the while it being clear that they spent no energy or time on the matter. What's the solution here? Some mandatory third party appeal service which you can call upon? Many victims of wrongful banning would be glad to carry the costs of a review by a real human to get their accounts back.
