I had one of 'those' buyers yesterday. They bought an item that was listed as pickup only, paid via Paypal, then sent a message saying 'when will i receive'. Straight after that was another message saying 'cancel it because I'm in QLD' (I'm in Melbourne, which was information clearly available on the listing). So I do so, I cancel the order and refund the buyer. Ten minutes later I get another message saying 'cancel the order' then another message after that saying 'when will i receive it, tell me'.
I have advised them multiple times that the order has been cancelled on their request, they won't be receiving the item and that they now need to accept said cancellation, but they don't seem to be the sharpest tool in the shed. So what happens if they don't accept the cancellation? Would it be possible for me to contact ebay and ask them to read the ridiculous messages and just process the cancellation on their end?
