How do I get out of DigitalOcean (DO) or why are they stealing my money?

Question

DigitalOcean

3 months ago I registered for testing on digitalocean, authorized my own there as, because. You couldn't register without. Tested and forgot.

Now I receive an SMS that money has been debited from me ($12). I go into the account, I look and the truth is that the money is in the account.

1) Why do they shoot without warning and any SMS?
2) Can I get a refund?
3) How to disable these payments?

UPD: Money returned. I looked at the list of accounts, they tried to write off $20 per droplet within a month, they didn’t succeed, they decided to write off as much as they could, just to write off

Answer 1

A typical hysterical consumer from the post-Soviet space.

Answer 2

You launched droplets that cost money, they beat you, what's the problem? Destroy the droplets and no one will beat you.

Answer 3

Excuse me, did you add the card to the means of payment yourself, created a droplet that costs money and then say that money is being stolen from you?
No, they just take payment for services from you, and do not steal.
Remove droplets and no one will charge for them.

Answer 4

1) Because they work by subscription. You agreed to this when you registered. Everything is fair.
2) And on what basis?
3) Having finished cooperation with DO. Refuse their services.
