False tax ruling

On 19.11.20 I allowed my van – an American model too – unfortunately a massive mistake was made here during the registration! Since I did not let the car myself, I noticed the error only where I received a tax notice from the customs over 811 Euro! I immediately to the registration service because I am friends with them! Uups there is in the papers n error! Immediately shine into the landratamt and let change! Now it is again correctly classified! The error was not by accident 0088 un On 14.12 he then passed the h report and the acceptances for trailer towing device so let change again … How is it going to go on???? Since the tax notice about 811 Euro is still in the room and I do not usually have 235 or 191 even so 500 Euro left for the customs! On 24.12 I received n write the my objection which I made obligatory on 30.11 abe r because of corona etc the processing can take months Say not now Book 811 too wrongly off??? How do I deal with it …
