I told Amazon was going to post a video to social of the third bad delivery at my apartment. It was so comical because even Amazon had posted signs on our property telling the delivery drivers what not to do. Yet the drivers did exactly that right in front of the sign.
The first two email complaints went unresponded to. After threatening to put on tiktok, I got a phone call from the regional director in charge of the deliveries within two days.
I don't think that was necessarily due to your threat. I've noticed that often the first one or two or even three messages about an issue that I send to Amazon seem to be answered by bots (or people following a poor script) and they miss the point of my message completely, each time, no matter how clear and exact I am.* It's only after multiple messages that a real (free-thinking) human seems to actually read it and respond appropriately.
* I swear it seems like there's a simple algorithm that scans the message for trigger words and then chooses a response based solely on those trigger words. I've received responses to issues completely unrelated to my entire message, except for the fact that they're about something I briefly mentioned in an aside or something like that. It's horribly horribly frustrating, even when I know it's going to happen.
No, the person who called me specifically said they were freaking out trying to get ahold of me because the social threat had caused the email I sent to be bounced around internally. She called me to talk me down from doing it and make reassurances, even though I had forgotten about it by that point.
Because they only had my email address and building location, Amazon repeatedly called the property agency, who (stupidly) gave them my phone number and details.
A popular PetaPixel post that gets coverage on additional social platforms is your only form of recourse against Amazon.
