Perhaps... Can I blame the Irish heritage?
I'm happy the seller offered and granted a refund. I would do the same in the case if I were on the other side, and I have been.
I sold a pair of Crockett & Jones shoes a few months ago that I thought were brown. Buyer opened a case because they were burgundy. I granted refund, and resold them after I got them back. My normal policy is no refunds, but there are cases where they are justified and freely given.
Maybe I'm harsh in communication online. But I had a very strong sense that I was being played by the seller. I've seen three different names for their business, along with three different locations. They claimed no knowledge, but then stated they had talked to someone with knowledge. They went from no refunds to offering a full refund within the span of 30 minutes. This whole thing reeks of two-week old rotting mackerel.
That being said, I still reported them for violating TOS for item location misrepresentation. There was no communication beforehand that the item was coming from Poland rather than England. If I had seen that, I would have cancelled the transaction.
