I have had no contact from a buyer who won an item I was selling on the 2nd October. I sent her a polite message asking if she was still interested on the 11th, but no response. I have had a look at her feedback and it is incredibly mixed, but more negative than positive over the last month. Before that, she comes across as reliable.
Please advise me on next steps. This is the first time this has happened, but I've only been selling since August. Thanks.
