Yeah but here's the thing, the details for payment of such things is always clearly disclosed on whichever notice they've received, and probably this was sent multiple times. Also the lawyers appointed by xitter are Brazilian, in a Brazilian firm, so they are familiar with how this works and the system is not dubious or misleading or confusing at all.
Like I've said, they're either grossly incompetent to a point that they can't read anything, or they're trying their "best" to avoid paying the fine but their best is comically pathetic at most.
Or they could keep reading the notice(s) and check out all the clearly stated details on who, where and how to send the fine payment
