.............................. I sold a pair of boots, got paid immediately, posted them to Australia in September. last week they arrived back to me as undeliverable. No contact whatsoever from the buyer. I emailed her telling her the parcel had been returned to me & asking why she didn't collect it from the Post Office after attempted delivery failed, no reply. This is so weird that someone didn't get their goods & hasn't wondered where they are or asked for money back. What do you think I should do?
