Thanks to both of you for responding, I really appreciate it. However, things have gotten a little more complicated... 😅
I actually manage two separate houses, each with their own listing. On top of that, I have a third listing that combines both houses, allowing for up to 18 people. The guest ended up booking this third listing, so I manually blocked the other two listings (one for each house).
When we agreed to open one of the houses back for bookings, I manually unblocked one of the single house listings. But wait, there's more! 🤣 After some time passed and we couldn't rebook those dates, the original guest agreed to offer a last-minute discount of 20% for "her" dates. We were then able to rebook 2 out of the 6 days with the discounted rate.
Now, when it comes to taxes and fees, I'm not even sure what the correct amount is to refund... 🤣.
