I recently listed and sold a book through eBay. The total costs plus postage only came to £2.49. The buyer took ages to pay, lots of excuses, and then eventually I received a letter containing the payment page but no payment. I emailed her to let her know, and she said she was going to speak to Post Office. I received no further contact so listed as non-paying buyer. She didn't respond to this either. I've just received a nasty email calling me a liar and a thief and threatening that she knows where I live! Whilst she lives the other end of the Country I doubt she will travel all this way for £2.49. However it still unsettled me because of how vicious it was. Do I report it. And if so, how?
