I've inadvertently purchased a lot of low quality junk from Amazon lately propped up by fake reviews and shady third-party dealers peddling counterfeit goods. If they want to sell me vitamins and food, they need to fix their brand. Are they a supermarket that is in control what they sell, or are they a back-alley bazaar that's strictly buyer-beware?
Be careful if you return too many of those shitty products, they will close your account, even if you have a Prime membership. Amazon is shady as fuck and an untrustworthy retailer. The way they treat employees is beyond atrocious. Amazon makes Walmart look ethical and honest in comparison.
My return rate is around average (I guess) and I've never had a problem.
The last incident is where I put the wrong sim card in a phone and couldn't get it out. Just return it I was told and the refund came through as soon as I had printed the label.
This is 100% the direct opposite of what would happen with any other UK retailer.
