Other members cannot possibly know what you ordered 

Maybe give us something (details) to go on?

I'm sorry, if you do not know what you bought, I don't know how you can expect us to know

Did you get an email from a scammer pretending to be eBay?

Did you sign up to something like Smartycashback or eBay Plus without reading the terms and get charged the fees you agreed for doing so

Something else?

As sandy says, we need more information… Help us to help you!

Maybe you bought as a "guest", if so it won't show in your purchase history.

Go to the link below to sort it out.

Would you like us to make some guesses?

dunno....maybe a harp?

Singing fish?

Banana-scented shower cleaner?
