I am a new seller on Depop and as I was packaging a sweater to drop off at the post office I noticed a small hole. it must’ve happened after I washed it. I messaged the buyer and let them know and apologized for the mistake and offered to either refund them or give them a discount. now it’s been about a week and they still haven’t responded. their account says they haven’t been active. I’m worried it’s been so long they’re going to be upset once they realize it hasn’t been shipped. I feel terrible. how would you proceed?
