Really bad services
First time my international train was cancelled just minutes before departure. Reisezentrum didn't offer any compensation. Today my expensive ticket from Belgium has no value because I missed train from Frankfurt because weird ordering trains on platform. By logic where is sign with name of train there should be train. Not in this company. I must bought another one and I'm not millionaire. Anyway platform is used for many trains. Only in Germany. Bad internet connection in trains. Cancelling night trains on way. Local trains are dirty. One star for train crew they are helpful and nice.
