I honestly can't remember the exact situation, but I believe it was related to mistakenly buying something that was an add-on or dlc for a game I didn't own, thinking it was a bundle with the game AND the add-on. It may even have been my fault, though it was certainly misleading.

But it was about $13 on an account that has spent literally thousands. They blocked my account and I couldn't connect to their network with my ps4/ps5 until I bought ~$13 in PlayStation store credit and added it to my account.

Great way to treat a loyal customer. It's almost like they know very well that they have all the power in this dynamic, and that I wasn't going to give up thousands of dollars in games over 13 bucks.

When they get a customer locked in like that, they know they can get away with anything, and they do.

You can call it what you want, but it's not unethical. I'm not even sure what they did would even be legal in Europe
