Sold item Returned to sender

Hi all,

Yesterday received an item, returned to sender.  It took me awhile to locate the relevant transaction, as I was not going back far enough in ebay or AP.

Turned out the item was sold and shipped to a parcel pickup point  on the 19th of June and was delivered to  the pickup point, but never collected and subsequently returned as unable to be delivered.

Have never heard from the buyer, but thought I would contact them to see what they want done, IE repost, or

refund minus fees and postage which was a bit over $50.  Anyway when I try to contact  with reference to the transaction or item number, there is no option to proceed with a message  and if I try to contact not in relation to an item, I am confronted with what appears to be a message to the buyer from AP, all to strange late at night, and I am dubious about contacting (not in relation to item) and then crossing swords with ebay when item transaction details are raised.

I know I can sit back and  do nothing, but I would prefer to get the item to them or arrange suitable partial refund.

Any ideas.
