Oh yeah. Dark patterns abound on Amazon. It’s really not shocking that an honest person would have trouble making it through their customer support maze.
If the seller doesn’t make it easy, the buyer might need to talk a human at Amazon and/or file an A2Z guarantee claim or whatever they are called these days to get a full refund.
The system is setup to save Amazon as much money as possible and push people to being Prime members. Unhappy with the third party seller scamming you? You should bought a Prime subscription and only purchase things fulfilled by Amazon. /s
P.s. Sometimes the easiest option is literally to call Amazon. They do have a number (in the US at least), but it can be super hard to find on the site. 1-888-280-4331
