what do you do to verify a damaged claim?

hiii :) i’m new to depop and this sub has been super helpful. i’ve sold about 6 items so kinda feel like i’m getting the hang of it. recently i had someone i sold leggings to message me saying that when they got the leggings there was a small hole. i didn’t rly know what to do so i gave them my phone # in a way that didn’t get flagged to send me a pic for proof. realizing now that that could get me in big trouble, so was just curious how you verify ppls claims about an item being damaged or not being described correctly? i get why depop doesn’t allow people to send pics in the dms lol but don’t rly understand how to address this situation in a terms friendly way. thank u :)
