The xitter lawyers claim that there was no bank account indicated anywhere so they "had to guess" and are demanding xitter to be unlock as they paid the fine.

In other words, either they're grossly incompetent and can't read, or they're playing malicious by trying to abuse some loophole or anything to ultimately not pay the fine

EDIT: For some clarification, there is no information publicly available as to where the lawyers sent the money to, only that it wasn't the account linked to this fine, and that the lawyers are demanding the service to be restored because they claim the fine was paid, but the correct account hasn't received the money, so the fine is not paid. Alexandre de Moraes has asked Caixa Economica Federal (one of the government banks and the only one that deals with this kind of thing) to "fix" this issue so the attorney's general office can analyse the process and decide on restoring xitter's service. Elon Musk, X and the law firm representing them in Brazil are in absolutely no position to contest, much less demand, anything from the supreme court or the attorney's general office. Their actions have shown time and time again that they have no intention to play fair and regularise the issues, and they'll try what they can to create instability, animosity and general distrust against Brazil's judicial system.

The information regarding payment details for fines is ALWAYS clearly detailed on every notice, there is 0 chance that they forgot to include it or they've made a mistake and added a different account.

The more I read into this the more it looks like the law firm is being malicious instead of stupid, they're trying all that they can to not pay this fine (on behalf of X & Co.) and also create instability/animosity against the supreme court, specially considering what Musk has done and been doing for this whole case.
