Why does Amazon keep charging me???

I keep getting charges from Amazon after removing all my inventory that seem incredibly unreasonable. For background, I used to sell products on Amazon but pivoted to another stream of income that I prefer. I saw that Amazon kept charging me despite my account being deactivated, so I reached out, and they said it was because I still had some inventory (I literally had one single piece of inventory left). I decided to just ship it to my home and be done with it. Weeks later, I get a charge for $58.13, mind you, it’s a small package that fits in a smaller size Amazon bag. I’m confused why I’m still getting charged because there’s no way they charged me $58 for that small shipment.

I ended up taking all of my cards off, but I’m worried they are going to continue charging me for random things in the future from my bank account. Every time I try to contact the help desk, they say I need to add a charge method and wait 48 hours. I did that, and now they’re saying it’s not working. I’m not dealing with this anymore!
