Called 5 times, each time more than 40 minutes on hold. Called again today, after 49 minutes I finally got in touch and is said by "sorry I'm going to call you back next week, I now have to set priorities and help customers who are really in the cold".
The function to be called back by pressing "1" does not work. 4x not called back. Please Itho Daalderop, do something about the quality of your customer service!
