Dealing with the outcome of a bad rating/review

I've been active on Fiverr for a little over three months now and my reviews and ratings on my gigs have been great. As of four weeks ago I have also been cleared to be a Level 2 seller.

One thing I have a problem with is that a recent customer gave me a horrible review after she did not give me the requested information to write her bio within the time period agreed upon/due date period. So, to be nice I sent her reminders and I even sent her a bio template to fill in the blanks since she did not respond with her basic info for the bio as she said she wanted. After the deadline date she sent me message saying I never contacted her and what I sent would not work and she wrote me a horrible review. I refunded her money to her after she expected me to continue to work on her project after the due date. This one action from a crazy gig dropped my score for one of my hottest gigs down to 80%, which in my book makes me look trashy. Is their a fast way to get my score back to at least 95% for this gig in particular? My overall rating was reduced also to 95% from 100%.

After this experience my sales have dropped from 2-3 per day to about three per week.
