I had a similar experience with a hairdryer (I am bald). They refunded the cost of the item I actually ordered (not a hairdryer)(I am bald). They offered that I keep the hairdryer (still bald). They were insanely against picking it up/returning it.

I guess that in their model of profitability they have included "items gone rogue" (returns are calculated in the financial statements, auditors "love" returns - especially for purchases made on year -1 and being returned on year 0)(I assume write-offs hurt less the bottom line/the auditors are less angry as long as it is not a fraudulent write-off).

Back to the story, a month later they sent me the item I ordered, free of charge and a friend of mine got a lovely hairdryer on her birthday. And I honestly didn't know that hairdryers can cost more than £€$100!!!

Returns are super painless now. You just click a few times on a webpage and then go to your local UPS store (or whatever you picked) show them your phone so they can scan the QR code you got sent, and then hand them the item.
