Complain about Buses

Hi everyone, I am living at Eilendorf and in morning we have to drop our daughter to Elisenbrunnen as she goes there to kita. There are only 2 connections bus 2 and 7. And everyday they are late for around 10 mins and sometimes buses don't even come. We have to run between stops not to miss the other one if one bus is late or not coming. Given the winter weather, wind and the early morning, it is not very good for my baby. Is there a way to complain about these buses? Or at least get a correct bus schedule if it is not coming?

Thanks.
