Incorrect payment operation. Paid twice!

[b34c1517]

Upswork have received payment from my customer for the second time. This is an incorrect operation. The customer wants me to refund the money. But Upwork billed me for this transaction. Although I want to send the money back, due to the invoice issued by Upwork, the money sent is incomplete as much as the invoice amount. Why is such a mistake being billed to me? The error is not my fault, it is an error between the client and Upwork. Is it possible for Upwork to undo this action?

Hi Murat,

Thank you for reaching out to us. I took a closer look at the transaction you're referring to and it looks like the client has been billed based on the activated milestone amount. It looks like the client has released the payment for the milestone which is also the budget for the project. You and the client may check this help article for you to be more acquainted with how to get paid on a fixed-price contract.
