Hello @Tommy235
How unfortunate for you and it goes to show why having a real photo on the profile is so important!! Once both reviews have been published you can't modify them unless you choose to delete the review completely as Airbnb CS have said.
You have apologised and you can put it down to a cultural mis-understanding as the first name François has it's very common female version Françoise and if you are not French you wouldn't necessarily know this especially if he didn't post a photo!
I'm hoping that the messages between the two of you were in the Airbnb messaging system so it will have no visible effect for future guests but you're right, the less said the better re names etc😉
We live and learn!
All the best
Joëlle ( male version of the first name = Joël)😁
