HELP ME to remove my negative feedback posted on seller's gig


My seller was later a day to deliver the gig and did not notify me about the late delivery. I thought something went wrong so I cancelled the order. Negative feedback was posted automatically but the seller contacted me with the work completed. I do not want this to ruin the gig as he already has like over 100 orders in queue. I understand that something would have gone wrong.

Contacted support to remove it but is there anything else I can do? Thank you!
