Well, Wednesday evening we found an overlooked Jahresabrechnung from the Stadtwerke which luckily I opened straight away, since it asks for 16.000€ to be paid by the 10th April. We had a Zählerwechsel last October, and kid#3 who was here at the time doesn't have a photo of the number at the time.
We made the earliest appointment which was for this morning at 10.15 which was obv a lie because it's closed for Karfreitag. Next appointment Monday, not falling for that again
We've booked the next available actual real appointment - Monday 13th.
It has been suggested that we do a Widerspruch against the Rechnung straight away (well, for Tuesday given they'll be shut until then).
Anyone had any experience with this sort of thing? We have photos of previous years and obv Jahresrechnungen and so can say last year was x€ so this doesn't make sense...
Or we wait until that appointment and explain then? Although it's after the payment deadline? Or go on Tuesday morning when it opens and ask the person on reception what is the best thing to do? Assuming there is such a thing - we've not been for 10 years or so, so the online appointment system was already a surprise...
