I listed some seeds on eBay that were listed as only shipping within the United States, as it is illegal to ship Nepenthes seeds between countries without proper permits. I also don't want to deal with international shipping or the costs of that... By the time the seeds got there, they'd be significantly less viable anyway.
So my problem is that someone from China who cannot speak English decided to buy two and never pay. On the day they requested an invoice, I sent them a message (in English) through the eBay resolution center, telling them we needed to cancel the transaction. No response a week later. I sent them another message yesterday before 9:00 AM in China. I used Google translate and had a friend validate that what I was sending made sense -- I told them I don't ship to China and we needed to cancel the transaction. Still no response.
These messages are being sent through the eBay resolution center... I don't see eBay doing anything about it. What am I supposed to do if they buyer doesn't / won't / can't agree to cancel the transaction? I never offered international shipping. They either can't speak English, or don't care the cancel the transaction. I'm fearing I'll get feedback saying "BAD!!!" within a couple weeks and I won't be able to do anything about it.
For those of you experienced with eBay, what do I do in this situation?
