Client Unresponsive After Completed Prepaid Project – Need Advice

Hello everyone,

I’m looking for advice regarding an issue I’m facing with a custom project.

I completed a prepaid 3D project, including multiple revisions requested by the client. I also delivered additional work beyond the original scope as requested.

After final delivery, the client said they would review the files (including 3D printing) and asked me to wait 3 days due to holidays starting April 14.

It is now April 21, and the client has not responded to my messages. The project is still open with no confirmation or closure.

I have already contacted support but haven’t received a response yet.

Has anyone experienced something similar?
What would you recommend doing next to ensure the project is properly closed and payment is secured?

Thank you for any guidance.
