It depends on how active the officials at FU are. It happened to me several times that I missed something or wrote something wrong and it was never a horror unless it was a trifle. They used to steal my company car and I posted it wrong. At that time, I got a patch of about 10,000 + to pay the tax on a stolen car as if I had sold it. I felt robbed twice because the insurance company, although it had to pay, did not. So there was no compensation and I still had to pay the tax as if it were. Eventually, the insurance company received a court order that it had to pay damages. After four years.
