People may be having trouble understanding what you mean.
I am going to describe what I think you mean. You will tell me if I am correct:
"My name is Said.
I am a client.
I created a fixed-price job for $100.
I sent a Hire offer to a freelancer, which funded escrow for $100.
But I changed my mind!
How do I get my money back?"
Said: Is this what happened?
I checked your account and can see that you have paid for the first milestone of a fixed-price contract, and have funded the second milestone. Are you looking to refund the first and second milestone that you have setup?
