We sometimes have similar problems here. My brothers wife works in management at a local major sorting centre; a fe months ago, my brother was awaiting a package; knowing it was on the premises, his wife spoke to the floor manager to ask about the package & to find out if she could take it home with her;
"NO" was the reply.
"Why? It's sitting right there; why can't I sign for it & take it home?"
"Because it has a delivery address which it has to reach & this is not it"

Sorry to hijack, Nick but, I had a similar situation recently which, ironically, had nothing to do with shipping, that only took a day & a half...
AFTER I sorted all the BS...
The handles on my front fly screen door had seen better days so I set about finding a replacement unit; they only come as a complete unit, handles & lock mech; we had the back door unit replaced around 2 years ago, which cost around $150 & I wasn't willing to pay another locksmith to do a 5 minute job, especially when I found out I can buy the unit for $35...
I found a suitable unit from a reputable local ebay seller & made the purchase on the 29th of January. While attempting to pay for the item, something went awry so, I paid for the item via bank deposit & included payment for express delivery as I was going away on the 4th of Feb; I then sent them an email explaining the situation & supplied all the relevant details needed to complete the transaction; the 4th came but, the lock didn't...
When I returned a week later, I had received a penalty on ebay for an unpaid item

I sorted that with ebay CS, then I went for the seller. I received very little response from the seller via ebay so, I rang the company direct; the guy on the phone tried to pass the buck until I explained the situation, at which point he said "leave it with me, I'll get back to you..."
Later that day he called me back saying they also had a problem at their end & the sale hadn't registered at their end (so, how did it generate a non payment dispute?) but, it was now sorted & dispatched; it arrived the next work day (Monday)...
So, two weeks of waiting, an ebay infraction, a lot of anger, frustration, yelling &
unnecessary phone calls all because some idiot didn't read an email...
...& I wasn't compensated in any way...
