The same problem as you, I passed through Hungary on August 24, 2024, I paid the vignette and that woman maybe it was early in the morning and didn't drink her coffee because instead of 0 she put O on the car number, I only received the fine in November, I appealed, no answer, I decided to pay so as not to have legal problems and I made the payment directly to the bank account showd on the fine and when I called customer services they said that the fine was not paid, I sent the proof payment, but it seems like you're talking to the walls, no one answers the e-mail and the customer services don't help you at all, I suspect that the fine will increase even if I paid it.
