Client Requested refund from past work (2-3weeks ago and payments has been processed already)

[cal-john_adrian]

Hi Upwork Team!

Good day.

I was just wondering how this is possible.

The client requested a refund for my past work.

Payment has been processed already and I have already withdrawn it.

The client's reason for refund says didn't work on the job.

But It is clear on the screenshots that I was doing it. 

I thought refunds are only possible for fixed prices and for those pending approval.

What step should I take next? 

When I click the link it takes me to the page. (image below)

Kindy asking for your assistance. 

Thanks!!

Any feedback guys?

The client was either likely a stolen card and their bank just noticed the charge, or the client/bank issued a chargeback. Either way, Upwork will now charge you the money that you received.
