First off thank you for coming and posting on the forum about this so we can discuss it better. This happened last night on the first map of no mercy. The girl you were referring to was chick who is a regular on the server.
From what I heard a few people on your team were complaining about you rushing. As you mentioned you were in the safe room (I did not look too hard for other people, just heard names being screamed and saw you in the safe room). The rest of your team was getting beat up pretty bad up on the street level and was asking you to come back and help. When you started mocking your teammates was when I decided to ban you because I felt like you were "trolling" and rushing on purpose.
The initial ban was two days because when I ban I usually overreact and am just trying to get you out of the server. However after the round ended I did change it to 15 minutes. You are free to come back and I am sorry for the misunderstanding but if your team is asking you for help it is better not to mock them, that alone will get you banned by my standards. If you come back and play with us I am sure we will learn eachothers gamestyles and I will be less likely to ban you if I know who you are. Hope to see you around
