Millestone not refunded after closed dispute

[#1]

Hello.
I recently had a dispute with a Freelancer because he did not finish the job.
We had a mediator in the dispute and later I and the freelancer came to an agreement and agreed that the $ 400 millestone would be returned to me (client). We then forwarded this decision to the Upwork mediator and he closed the dispute and sent the following information on 16 July:

'' Per the mediation process, both parties have agreed to return the funds in escrow back to the client. $ 400.00 has been refunded to the client and the dispute is closed. ''

The problem is that the dispute was closed on July 16 and so far the 400 dollars have not yet been returned to my paypal account!
What should I do?
