Mercari Blocked response then claimed I was late to file and refuse to address a buyer who damaged my merchandise Palo Alto California

Sold a NEW Calvin Klein leather bag on Mercari. Orig price $238, sold for $115. Manufacturer's tags & labels were attached. I described the item completely & added photos of all sides. Sayoko Campbell, Cleveland, OH, bought the bag off the Mercari site. Soyoko must have damaged the bag, so she claimed the color was turquoise, not green (green was labeled by Calvin Klein & the photos). She also claimed (qualifying reason to return by Mercari) that the bag was fake.

Mercari, blindly accepted the return & refund of the bag. No problem Others were interested. I received the bag back with marks all over the back and bottom. The marks were like bleached etchings or something?How could I sell it to anyone else? Even if I used cleaner, it would dull the leather. It was no longer a new bag in the perfect shape I sent it. Mercari gives 24 hours after a return to respond.

I immediately tried to contact Mercari & sent images. I CON'T to get a message "Error, try again in a few minutes" &NEVER GOT THRU! I didn't give up! When I got thru, Mercari claims TOO LATE! So instead of 24 hours, my response can slightly over that 24 hour mark?  But their web site wouldn't allow transmission of the response!!!
