Unfortunately it looks like you stayed quite some time ago, and when I looked at the host it appears she no longer even has properties listed.
First, you should never pay anyone anything outside of the AirBnb platform. When you do this, you throw away any security airbnb provides. If a hosts asks you for funds outside of the site, I would let airbnb's know and request to cancel.
Second, if something like this happens, document it through airbnb, and make sure all your correspondence is done via the messenger. This provides you backing should the event escalate to a bigger problem, or claim of some sort. I have guest who often text me outside of the platform. I also have host who do so. I always make sure to re-direct them to airbnb.
Lastly, always leave honest reviews. It looks like you did not leave one for this host. So going along with what Andrew said, it is going to reflect more negatively on you, because there is only one side to the story. As a host, if I looked at your profile, I would probably be hesitant about accepting your request. You can also respond to negative reviews on your own profile, which will give future host a little insight as to what the situation was, and might result in them being a little more open to hosting you.
