Airbnb is blowing up my email, sms, and app with duplicate messages

[Mark-And-Sharon0]

I've received the same message from a guest 7 times.... 4 times in just the last 5 minutes.  I know it isn't her sending them because it's very late where she is and every message is exactly the same.

This is not the first time it has happened, but I only received one duplicate then and ignored it.

Who can I contact to fix this?
