Yall i need help to get my weapons back

I had kitty purse and glitter and this girl asked to offer for Kitty and i declined her offer but she had a skin i like so I asked to offer for it but I had removed the purse and she ended up with it. I asked her friend to call her back to the server but she didn’t want and kept making excuses. Later she joined and I added her and she said she had lost all her weapons but I knew she traded them away then I see her using a kitty purse and I speaks is that the one I traded she said no she had gotten it from her friend. Mind tou she said she’ll work to get my weapons back but with the weapons she has it would be so easy to get it back. So any donations would be gladly appreciated and I wanna raise awareness too so..
