I had a seller on Amazon give my info to another party who then mailed me unrelated erotic marketing materials with my name and info on it, weeks after my order. I told customer support, and they instantly went "we'll handle it, have a nice day" before I could even tell them who the seller was. I knew who the seller was because despite my info being in the digital order form on the website, they somehow managed multiple typos and mistakes, which the unsolicited mail also had.

It's all pre-scripted bullshit to prevent customers from doing anything about legitimate issues.
