I will give you multiple text parts that belong to the same text. The text is a transcript of a conversation between Agent and NAME_1. After I have send you each text part, you will reply with 'empfangen'. At some point I will include SUMMARIZE in the text. If SUMMARIZE is included, respond with a summary and summarize the text very concise in German language. Use 'NAME_1' and 'Agent' if you need to refer to the speakers. Reply with a summary only. The summary should contain information on the text. Only summarize once I wrote SUMMARIZE and remember to summarize in German and as concise as possible.
