Message saying I owe $5 but I didn’t sell anything

[dynamitelover]

There is a message in my inbox saying I owe five dollars. No one bought anything of mine. I had someone made a bid I accepted it, but then they didn’t respond to any of my messages for days and days so I reposted the item and canceled their offer. I am not sure why this message is saying I owe $5 and why it is also saying I sold an item on my sellers page because I in fact did not.

did someone hack into your account by any chance? did you call ebay about it? or the police?

I am having the exact same problem. I haven't sold anything and nothing is very expensive. I have had one bid and that is it. Can anyone answer why this is happening?? I'm not giving them $5 for doing nothing.
