Verbal Harassment on Night Tube

I was on the night tube a month or so ago on my way back from a friends house. Two men came on and I immediately didn’t feel very safe. They were incredibly drunk and loud and one of the came and sat down next to me, the other in front of me, even though there were plenty of seats all around. I put my headphones in and started to read something on my phone. I didn’t want to engage, but they didn’t let me. The one next to me pulled out one of my headphone and kept talking to me, making comments about my appearance. No one did anything. My space was totally violated. Eventually I just got off the tube and got into a different carriage, but I was so worried they would follow me or berate me that I was on edge the entire way home. By the time I got to my flat I was totally exhausted from being so on edge.
