Just that, really. Just got an INR message out of the blue from a buyer complaining about an item not arriving. I checked and it should have arrived on the 16th November (posted 14th November, day after payment).
The buyer has 1000+ feedbacks and it's very low value. I'm going to refund - it's not worth the stress to argue it.
But just out of interest - can buyers really come back at sellers after such a long time? Did he manage to hit me on exactly the 45th day or something?
