It's a third-party booking, @Mariam160 , and so that was the first rule broken. The second was bringing in the extra guests. Ask her to leave. Get it in the messaging with Pamela, and get help from a friend or family member if you can. From the police if you need. Yes, I do think you will have to phone Airbnb, but you should get fairly quick help since it is a problem with a current reservation. That seems to be the priority right now.
You should not have to quake in fear in your own house. I understand why you think it's an option, but it's no way to live, or to host. Will you do that and let us know you are okay?
