I would not go that far to say it's fraud. Calm down.
Maybe it's something I missed. Maybe its some hidden feature that I did not turn off. But I deleted all my droplets, all my IP's all my firewalls, etc, etc and could not find anything else.
You have in good faith attempted diligently to have a zero purchase. You cannot even find any purchases. In that case they have reached into your pocket and taken money without your consent. That is just a fact. By mistake? It's being short changed in a shop at the absolute best.
This is not a mistake any company should be able to afford to make. Ever. Under any circumstances. If it really is "just an error" they need to making amends in a very public and obvious way that is clearly expensive to them to show good faith.
But we don't get that. We have to fight from a position of being in the wrong when we have money taken from us by these fraudulent practices to overturn them.
It is necessary to go HARD at the morality of "accidental theft" because it is so prevalent and because all these companies clearly don't consider it a detriment to their reputation.
You've been diligent. When does it become their responsibility to not reach into your pocket when you clearly don't want that. Or anyone's pocket. I'd bet quite a sum that where there is one there is many.
This is where I'd say that every single paid service needs to have a way to contact a human being, and any cancellations expressed to that person by an authenticated user must be respected. If services are allowed to construct Gordian knots of byzantine interacting services, then there must be a way to cut through that mess.
I'd double check that you don't have multiple orgs. You used to share a cess to your account with people, then they made some org change a while back that essentially moved that shared access setup to an org and gave you a new personal account iirc. Easy to not realize you have both.
