should do with customers who already have low reviews?

3 freelancers didn't get the job done for him, and I got a contract with this client. If I continue I'll be underrated by him.
what should I do.
the job he gave is very good, I did it he said it was perfect, but when I did 50% of the work it took too long, I asked for an extension of 1 day he didn't give it and asked for a review 1 Star.
made me pay back. and I agreed.
I think this client is looking for a job and refuses until the end with the cheapest price.
so bad

Public feedback will be hidden if you will issue full refund.

If you refund full amount to client then public feedback will remove from your profile. But private feedback will still affect your JSS
