Hi

I used an ebay print postage label for a return and posted it last Friday. Now it's Saturday a week later and the system still doesn't seem to know that I've used the postage label and won't allow me to mark my return as dispatched because it won't let me add the tracking number used on the postage label. What can I do?

Enter your tracking number at USPS.com --

does USPS confirm debilerance back to the seller?

The tracking number is already entered into the system.

You cannot enter it again, at your end, disregard the box that appears.
