About a week ago I sold an item to a buyer and arranged a time to pick it up and that it would be paid in person.

However, no one arrived to pick up the item at the designated time and I even waited an extra 2 hours looking out the front periodically since they may have been extremely late.

I assumed that they must have got the wrong address or got lost, but the details I sent to the buyer were correct and asked them via email as to why they didn't show up. Buyer replies back that they did, but that couldn't have been the case as I stated above. I even asked to arrange a more suitable time for themselves and that I was willing to hold onto the item for the time being.

I did not receive a reply back for about a week now and I'm wondering if I should even bother waiting any longer and actually do something about it?
