No, the way it was worded made it seem like the issue was with me. It says that I have to send the item, and will then receive the funds - confusing! This is an excerpt from the email I got sent.
You have received a payment from ************. The payment is in your pending balance and, if there are no problems with the order, the money should be in your available balance within 21 days. This will help us continue to be a safer way to buy and sell.
How can I get my money sooner?
You should be able to get your money within 7-14 days if you:
Send the item to the buyer's postal address as displayed on this page.
Provide the dispatch details and mark the item as sent on the Transaction details page.
It's just strange that I've never got that message before. x x
