I have reason to believe I got my identity stolen and used to open an account here. I want you to close that account immediately. I can prove who I am so any information or document you need please ask.
I do not wish to publicly display my information and I didn't find any other way to contact Upwork support, so once I get a reply to this thread with a way of contacting you, I will provide anything you need.
P.S. - Refusing to cooperate will result in a lawsuit against your company.
