Hi @Nate45, i'm sorry this is happening to you in what is already a stressfull time.
I used to work as an event manager and there is an unspoken rule (that is pretty much common sence) that you dont F*** up someones wedding.
Sounds obvious but wedding's are a not birthdays that come around every year, or awards dinners, or conferences. Weddings are something that affects someone, and their closest freinds and family for the rest of their lives.
If something looks even remotely like it might be going wrong you make **bleep** sure you've sorted it no matter what it takes to sort, because you dont get a second chance at fixing it, and from a business point of view you will never be able to make amends.
Airbnb should be all over this, if your case manager is being somewhat slow, contact airbnb on a social media platform and make them aware, to get it changed to someone who is all over it. @Quincy ?
Because for you it's such an important day, and for airbnb, this is the stuff that if it does go wrong they don't make amends by just issuing a refund, this is the kind of thing that ends up in the news.
I hope it gets sorted quickly!
