So I went to someones house to pick up something that I had bought on gumtree from some chick and I was threatend with violence to leave by her bf or something... essentially I just got scammed out of my money. I am actually furious!  

I  have her number as (08) 0481965999 and her address: 7 cartwright road balga, perth. 

Should I take revenge, and if so how? What would you do?!
