We needed help to get in the apartment and the door lock was not working properly. We asked for help and called Tina first. Then she asked me to call Sam for help. Sam told that he lives far away and won't be able to help us. I was waiting for a long time outside and after some time, one of the guests opened the lock from inside and helped us get in. After that, Sam suddenly came to the apartment and threatened and shouted at me and asked to leave to the house. It was around 12 am in the morning. He also sent me threatening emails and harshly told us to leave the house again. We were feeling totally unsafe in their house. It was due to my flight schedule that I could not go to the police station and complained about such unaccepted behavior. Else, I would have made sure that Sam paid for what he did.
