AWS from Amazon keeps credit cards even after they are deleted, and eats to withdraw money from it, how to deal with it?

Question

Amazon Web Services

I registered with aws, used their services (Trial period), then I took a server for a test and started mining on it, well, I deleted the credit card, time passes and an SMS comes from the bank about trying to pay $ 335, I think some kind of mistake and I live on, a month later, again, an SMS about an attempt to withdraw $335, and then, literally like a week, I receive an SMS every day at 7-8 in the morning about an attempt to withdraw $552.24.
Now the question is:
1) Is it safe to do so as they store a credit card even after being deleted by a client
2) Will it help me that I deleted their account completely
3) What should I do if deleting my account does not help me - destroy the card?
4) Will there be any penalty or liability for not paying?

Answer 1

It does not follow from the question that your server was completely free and was disabled after use.
Contact those. did you try support?

If you are not going to leave the country - you can score a bolt. True, almost no one wants to work with Russia because of such hammering bolts.
