Please this happened to me today, I've been working for this client since last week to complete her branding project and I was able to finish it today and deliver, she was happy with it and her response was great but to my surprise after some minutes she messaged me with unnecessary expenses and ended the project and and asked for a refund in the escrow. I felt like been cheated, I opened a dispute but she didn't accept it as well, please what is the next of action? And does it mean if she decline Upwork Mediation and I accept it, what would happen as I don't have that much to go for arbitration. Please help me, thank you.
