Long story (covers several weeks) cut short.
Someone sends me a camera, using Hermes, to deliver to a local (to me) parcel shop.
On delivery day, Hermes say there's a problem, and get in touch.
Problem is that they can't gain access (10:43 am, to Co-op with its own car park and on street parking outside, opening hours 6am to 11pm).
Check with Co-op - they haven't burned down or been accidentally demolished.
Go back to Hermes - sorry, the problem was that the Co-op refused to accept it.
Go back to Co-op - no they didn't, and they've NEVER refused a parcel.
Go back to Hermes - ah, it was the courier that refused the parcel, not the shop.
Back again to Hermes; admission gained that it shouldn't have been returned to the depot, but since it had, there was no way that they would do anything other than return it to the sender (this while it was still in their network).
Duly returned to sender; admission made that they made a mistake. Refund? No, out of the question - they delivered the parcel. But they would offer a credit against future parcels entrusted to them.
