Hi @Guillaume570,
Sorry to hear about that situation.
The Community Center is a place for Hosts to connect and support each other.
To get help regarding the refund you mentioned, you need to get in touch with the Support team. They'll be able to look into it for you.
Also, just a heads up that I've moved your topic to the English speaking community. This way you'll hopefully get more replies to your question.
I hope this helps.
Thanks,
Liv
