Told them the wrong items we're received. Actually got a refund on one item, but not the rest

I find for these kind of swaps, Amazon Warehouse Deals are good option. Amazon treats it as if it was shipped and sold by Amazon, but most of the items have been returned before so the chain of custody is broken so to speak.

This is absolutely true. It's exceedingly common for the wrong item to genuinely arrive so it just helps your case, you're also investing less because it's an Amazon warehouse deal and not a new item
