re: "They have have still not delivered the project in full and we keep noticing issues. They ended the project in July and we still do not have the complete website. They keep promising to fix it, but have not delivered in full yet. Can someone help me report them and file a complaint."
Aaron:
You are putting interest in one specific freelancer/agency ahead of the needs of your project and ahead of your own needs.
Don't do that.
Put yourself and your project first.
There is nothing for you to report.
There is no complaint to be filed.
You don't need to show any proof or information to anybody.
You don't need to communicate with Upwork in any way about any of this.
Nobody who works for Upwork is going to complete your website for you.
You hired a freelancer/agency to work on your website.
They did so.
They are no longer interested in working on your project.
You owe them nothing.
You do not owe them the opportunity to continue working on your project.
They are in the past.
Hire new individual freelancers (NOT an agency) to continue working on your project.
And hire an independent project manager to oversee the work.
Communicate to your project manager what you want done next, and allow the project manager to assign work to freelancers on your team. Quicklyl fire any freelancer if you don't love their work.
If you have any questions about how to succeed in accomplishing your goals, feel free to ask your questions right here in this thread.
