Wow...so this is what Facebook Marketplace support told me about my controller (pictured 2 posts above).
Thanks for sending us a picture of your item. I'm not able to see discernible damage to the item from the photo you provided.
Unfortunately, since the photo doesn't show clear damage to the item you purchased, we're unable to issue a refund. You can learn more in our Purchase Protection Policy in the link below:
So, I guess that tells you everything you need to know about their buyer protection. You can sell used shit and advertise it as new with zero recourse. This is why I take advantage of glitches, loopholes, and price mistakes. Big business will not hesitate to you. They deserve the same treatment. Looking forward to the next opportunity to them over.
