I got a negative feedback without deserving it

I just got a negative feedback for a silly reason and it really triggered me so i decided to open a topic here
I put the wrong price to my listing and this guy buys it
I did my best to make him understand that the price was wrong and i was sorry it ended up with his negative feedback its really unfair i really put so much effort in my account and this happens…
I have another negative feedback on my account and that one was an accidentally given by the buyer it
Please help me out to get rid of this feedbacks
