am i overreacting :/

i purchased a bag from depop last night and prior to purchasing, i asked the seller if there were any stains / damage since the post had no mentions of it. they said “none at all” and today they’ve sent me a message saying it’s been shipped and hours later, they tell me theres no damage but there is a stain “i’m sure you saw it” 😭 they’ve now deleted the original listing so theres pretty much no proof :/ is there anything i can do when i receive the bag?
