Undoing percentage increases in all my listings

[ArtisticSass]

Hi, all of my listings are messed up.  I increased prices on all of my listings by 5%.  then I realized my prices are strange so I thought I'd re-do and round the numbers up.  I did not realize the rounding would round up to the next whole number vs. rounding the cents.  Then my variation listings that had different prices, all have the same lower price!  There was never anything along the way to verify what I was about to do.  How do I undo everything to where I started?  There is no way to get ahold of a person at Etsy is what it seems like, and I'm in a bit of panic mode with my shop on vacation while I straighten this out!  Help!  Thank you!

I don't know how many listings you have but you might just have to do them individually. When I increase, I always group the same-price items and do those. I never use the % increase/decrease. I just put in the new price I want for those items. I like to have round numbers.

@ArtisticSass: To the best of our knowledge, there is no <undo> anywhere on Etsy. You may have to fix them individually or perhaps in batches that will have the same new price.

Can anyone tell me where it said anything about changing same priced items in batches?  I only got information about how easy it is to change all listings at the same time, etc. - and even doing it in % changes.  ABSOLUTELY  NOTHING about this disastrous scenario happening
