Hi Jade
I am not sure that AirBnB have the staff to deal with this problem - it seems to me that the 'system' takes control and human intervention does not get a say in.
I have tried to report what I believe may be a problem for hosts in the future... but there does not seem to be any means by which human intervnetion (by AirBnB staff) will resolve matters.
Have you done a review on this person yet?
If not... then you should do one and tell it as it is... and NAME her... so that other hosts can pick up on who she is.
There are always one or two in dividuals who will wreck it for the majority. Good luck resolving this issue
