Hi @Duska1,
I'm not sure I quite understand your question. Your guest has requested a refund? It would be great if you could give us some more information about this so we can try and help you!
Just to let you know, I have moved your post here to a new thread so that it doesn't get lost in another discussion and it is easier to find. I have also given it a title, please let me know if you want to change it!
In case you're not sure how to start a new thread - this CC Tutorial gives a step by step guide to starting a conversation in the Community Centre.
Happy Hosting!
