I had a buyer make a best offer on an item and I accepted, but after two days they had not paid. They then messaged me saying they hadn't read the description properly and didn't want the item. I was somewhat annoyed about this and opened up a case saying the buyer hasn't paid. Four days later, I have closed the case. I have now find out that the buyer will receive an unpaid item note on their account. Will it massively effect their ability to buy on eBay? And will they be informed?
