You can't.
You can leave a Response to any Feedback, your own or the buyer's. There does not seem to be a time limit on this nor do Responses have to be positive.
But.
The best FB and the best Responses are calm,polite, factual and professional.
Remember the only ones who will ever read them are future potential customers. Don't turn them off by being negative, angry or rude.
Responses are more likely to been seen by those potential customers because they stand out on the page.
If you are having a problem the Response might be "I regret you are unhappy with your purchase. Please return it for a refund." or perhaps "Offered refund on return. Did not return."
