Wow, that sucks. Parts Geek didn't really screw me, but I got a part that was really incorrect versus the listing-ordered a power steering rack, received a heater hose-and they did eventually refund me, but it took them a couple months. On the plus side, however, they did email me a return postage sticker that I could print out and attach to the box, so I didn't have to pay for shipping back.
I think Parts Geek itself is just an aggregator website and the people you talk to, are likely employees of the various warehouses. Which might explain why some of 'em lack customer service skills, they're likely being tasked with this online headache in addition to their regular duties.
