Yesterday your client sent me a reservation request for 5 nights, which I approved.
You blocked my calendar for that time meaning that the dates were unavailable to anyone else who might have been looking for a stay during that time. Your client (my guest) never paid while they were "shopping around" for a better deal but were allowed to freeze 5 days in my calendar for 24 hours while you waited for them to make payment, which never materialised.
This client has no previous reviews or Airbnb experience, yet your company allowed this to happen. This is wrong! no person without a valid payment method should be allowed to hold a booking under any circumstances.
Sorry, but you guys need to remember who supplies your beds. You don't own anything. Stop annoying your suppliers with ridiculous system operations!
