No Tüv due to wrong load index

Hello together, has someone already made experiences with the tüv because of wrong load index of the matures? I was yesterday with my opel omega 2,5 dti for take-off. I have raised winter tyres with the dimensions 195/65/R15 91T. now the tüv says, no can at all, it must be 195/65/R15 92T. Therefore I did not receive a Tüvplaquet. I checked my documents, but found no hint about it. I can read here that the index 91T/92T is a difference of 15 kg. is e s correct that I did not get a badge, or was the examiner not good at it? Otherwise no faults!!!!! Where can I inquire, I bought the matures last winter, but was not asked for the load index….. would be very grateful for a quick answer, as I should drive tomorrow with the summer tyres to tuv. have a short-term license mark, because the car is not yet admitted.
