I sold two albums to a buyer visiting the state's last month. I normaly do not sell to foreign buyers. He instructed me to send albums to a hotel here in the NYC area. Everything worked out and I left positive feedback for him. Now after a month he has an issue with one of the albums, the album is NM shape. He doesn't like that their is a blemish on the vinyl. I never noticed anything, the record plays perfect, it's 40 years old, it's from my personal collection. I offered him $6 back for a refund even if I am in the right. I have a feeling he's going to leave bad feedback. He's trying to make another deal with me but I want nothing to do with this buyer. Can you block a buyer? I have 100% postitive feedback, I feel like there is no one at discogs to help me.
