You were not hired, so there is nothing you can do. You won't get paid, so put the finished work in your portfolio, and take this as a lesson learned.
Oh, and read all of the Help articles and other available resources (like the forums) about how the site works before you do anything else.
I'm sorry to hear about your experience. We suggest communicating about this with your client. When working on Upwork, please make sure that you have a contract with a client before doing any work, and ensuring that they have a verified billing method so that the work you do can be covered by Upwork Payment Protection is also a good idea. I'd suggest browsing this thread which has helpful tips for new users and you can also check out this thread for tips on avoiding suspicious jobs and scams if you haven't already.
We are beta testing a new way to help you stand out to clients. Now you can optionally bid additional Connects to appear in one of three promoted slots pinned to the top of clients' proposal managers.Learn More
