Thank you for your response.

So this person was sending private messages offering me less than a third if the price on bundles. I was saying no and they were persisting. I blocked them. They went on to created five additinnal accounts (all the same postcode) and made lots of low offers which I ignored or declined then attempted to buy different items. I contacted ebay around ten times asking for support but kept receiving standard responses.

From using other platforms I have bad experiences of users making extremely low offers then straight away trying to buy at full price then claiming the item is damaged or didn't arrive as they are annoyed.

This was several different items and persisted over two days.
