So I sold this one pokemon card overseas (it was only 10$) and the buyer messages me If i could write a custom hand written note for his nephew and send the card to the address of his nephew's place instead of the buyers as a gift. I agreed to it because of it's innocent nature, and the 10$ was untracked lettermail and was willing to take the risk of it getting lost from transit. I wrote a hand written thank you note to the buyer's given name instead of the nephew's name by accident. It was a mistake that was careless from me and I learnt from it after this order. Unfortunately, others won't be that patient with mistakes, espically when it can be that little. the buyer got mad at me for writing a thank you letter address to him instead of his nephew. Since I knew that was a mistake I obviously apologize and told him it was my bad on my end. I even asked how was the card and did it arrive well. I did fulfill his request to write a custom note to his nephew as well, and there was no respond to all of that. He even went far to threaten negative feedback on me as a breach of security even though the letter was going to his nephew and his Ebay name was public for me to see. I followed along and was professional about it and he goes on to say If i sent him another card with the same hand written note then he would give me positive feedback, while ignoring my question about the previous order and the custom note I made just for his nephew. I just want a second opinion from anyone, but does this sound fishy? i Briefly read on the Ebay protection for sellers they are not obligated to add any additional items or things to the listing or order. If the card was damaged, that be a different story and I would have happily refunded the buyer if photos were provided. But the buyer is threatening me on something i added additionally while the card and custom note are assumed as described. That's just my view, at this point I have no clue what to do now I will continue to hear him out and see to it what happens after.
