Except maybe eBay. I wanted to call eBay and ask how I purchase a support contract so I could report a bug in their returns system, but there's no way to contact them for that. But yeah... they're at the same level.
I had insurance on the box but the buyer wouldn't return the box to Fedex for inspection. (Because it was fraud)
Getting this fixed was excruciating and ended up having to DM people on LinkedIn and guess their internal e-mail addresses to get this resolved. Absolutely horrible!
