The original label was bought via ebay, yes, $5.12 according to you, and this is where ebays involvement ceased.

You then claim to have paid extra, direct to the courier when lodging the item, nothing to do with ebay.

I note you have failed to answer if the item was a small satchel as claimed by you, or a large box as charged by courier, and why you paid the courier extra, if the item was indeed a small satchel.
