If this was originally listed as a postage item only, there is nothing you can do to mark the item as delivered.
Collection items when purchased and paid , buyer then receives a collection code to give to the seller who scans this, and this is the only proof the seller has the item was collected / delivered.
The buyer can leave you feedback, but this will only release the payout sooner, if the value was under £25, there is nothing else the buyer can do.
With no tracking or collection code to show delivery, your payout will be held for 14 days before release.
If you are a new or returning seller, you may be subject to longer holds of 30 days.
