Unfair Treatment on Upwork – Charged Unjustly and Disrespected by Client

I recently worked on a project through Upwork, and the client unfairly demanded additional payment from me. When I stood up for myself and mentioned I would pursue my rights, they responded sarcastically with "good luck" and used disrespectful language. I have all the evidence to back up my claim. I’m requesting that the payment I sent to their Kuwait Bank account be blocked immediately, and I also ask Upwork to investigate these individuals for their inappropriate behavior. I expect Upwork to take action and ensure freelancers are treated fairly on their platform. This experience has been deeply frustrating, and I hope to see this matter resolved quickly.
