"But certainly I would expect accounts would accumulate warning flags and at some point be banned."
They do exactly that, but sometimes, it goes wrong. It happened to me in October 2019 and I'm still trying to get out of this nightmare.
I bought a high-end desktop for $2700 from amazon, it was shipped with a GTX 660 instead of a RTX 2080Ti! The graphic card had been swapped by the previous person and Amazon blames it on me.
- They say they checked the item before sending it, they obviously didn't
- There was no indication when buying that this item had been previously returned
- They say I did this scam several times before but I order a couple of times a year and for low value. I never returned anything
- They refuse to listen to me and consider they made a mistake. The India-based chat support is entirely useless, they keep telling me "there is nothing I can do", "so sorry", etc. I sent an email to [email protected] and they tell me "we'll not be able to offer any additional insight or action on these matters, and any further inquiries on this matter won't receive a response."
After seeing how good customers are treated when their processes go wrong, I'm definitely never going to buy anything from them again
