Deutsche Bahn, were should i start?

I needed to go from Augsburg to munich but the rails were under repair so i had to take a train to Donauwörth, for 40 minutes, then from there wait 10 for a train to Ingolstadt, took 30-40 minutes, from there wait 20 min because the other train didnt wait, and from Ingolstadt to Munich that took 2 hours because only one rail into munich was open and so the train had to wait for 1 hour 30 minutes. All i needed to do in munich get a medical recepie... all that time for a piece of paper. Luckily way back was quicker
