For standard run of the mill customer support they're still pretty great. I was shopping for new wireless earbuds last fall and tried out a few different ones. 2 of the 3 were defective and I didn't like the third-- they hurt my ears to wear them.
For the two defective ones, I'm not sure why but the normal return button wasn't available and I had to go through chat support. I explained they were defective and I wanted to return them. They told me they'd issue the refund, no need to actually mail them back, so I didn't have to go through that hassle. And these were high end ear buds, a total of $400 worth of tech.
Amazon sucks. It should be broken up.

I expect them to at least collect the information that I received, or suspect I have, a counterfeit item, when I go for a return. They don't even bother to do that.
