I had an annoying situation a few months ago.
Large retail chain, but one which doesn't have branches in every city, this will be relevant eventually.
From their website, I ordered 2x Item A, 1x Item B.
They duly sent an email saying that my order would be arriving in two packages, (1) 1x Item A and (2) 1x Item A + 1x Item B. Following me so far?
When the packages arrived, (1) contained 1x Item A but (2) contained 2x Item A + 1x Item B. So now I had 3x Item A. I most certainly did not want 3x Item A.
I spent an excruciating length of time on their webchat being escalated higher and higher up the chain, trying to explain the issue. Yes, I wanted to return 1x Item A, how could this be done. No, there was nothing wrong with the items. No, I didn't want a refund, etc. Finally a supervisory person told me to take Item A to a store and just quote my order number.
Fortunately, this chain does have a store in my city. But at the other end from where I live and work, so very inconvenient to get to (and that's why I bloody ordered online for delivery in the first place). I must confess I didn't rush out immediately to return Item A because inconvenient, but a couple of weeks later I did have a bit of spare time so off I went to the store.
Nice fellow at the returns desk was perplexed. I explained all over again, in great detail. He took the surplus Item A, did all the computer typing stuff, apologised for the inconvenience.
Several days later, they sent a refund 🤦🏻♀️
Did I pursue it further to ask them to unrefund me? No, I did not. I felt I'd made enough bloody effort.
(I wonder - What if there hadn't been a store in my city? What if I'd had some reason e.g. illness or disability or just not having the time, why I couldn't have got to the store in my city? Could I have told them to get stuffed in those circumstances?)
