I needed to book a ticket for 25th of June but I booked it for 25th of July instead. I booked it through [booking.com](https://booking.com) who basically asked me to contact the airlines. I have been on hold for over an hour now, I do not understand German so I don’t even know if i have called the correct number. Can anyone offer any information ?
PS: I do not live in Germany, I am posting here since a lot of Eurowings reddit posts were on this subreddit
