I am very sorry that you had a disappointing experience while using Upwork.
But this is all on you. You used the Upwork tools incorrectly.
The client has not violated any rules.
re: "She paid me a retainer 300$ agreed upon and once i submit the full scope she ended the contract. The contract was for 1200$ and not 300$. I know that i should have asked to fund the milestone but I was busy and she was very friendly"
She did not pay you a $300 retainer. She funded a milestone with a $300 escrow payment.
The contract was NOT for $1200. She funded a milestone escrow payment for $300.
Maybe $1200 was the "budget." But budget doesn't count.
Maybe $1200 was what she promised. But promises don't count.
Maybe there was a discussion in messages in which she said she would pay you $1200. But discussions don't count.
re: "Now I know that I may not get my money back but i want to report this Client to upwork in order to help reduce scams and thieves, Who should I talk to?"
It is not Upwork's intention that you report this client.
It is not Upwork's intention that you talk to any Upwork personnel about this.
If you would like to talk about this, please feel free to discuss this here in this thread.
You are welcome to ask ANY questions that you have.
re: "in order to help reduce scams and thieves"
You MAY BE CORRECT in your assessment of this client's moral character. This client may be one of the most underhanded, manipulative, duplicitous scoundrels ever to use the platform.
But that doesn't mean she broke any rules from Upwork's point of view.
I don't see a "scam" or "thief" in this situation.
From my perspective, I see a freelancer who worked for free. I don't doubt for one moment that you are sincere when you express frustration about this. I feel bad for your perceived loss.
My recommendation for you is to learn from your mistakes and move on. I can't think of any way that you will benefit by trying to contact Upwork personnel about this matter.
