Customer service is impossible. Emails? Will not be answered even after two months of waiting. Phone calls? I am happy when I get through this hotline. Then you can count yourself lucky that you understand a word at all - that is not German (despite the German telephone number)!
Follow up with queries at the hotel? Does not happen. then I tormented myself for a few hours through the queue. It's a shame they couldn't help me. Now you sit firmly at this hotel (that a rebooking had already been agreed in advance) and can't do anything with it. But hey, thanks for the great customer service. Never again!
