Charged me 4 times

Hi I tried to sub a few times but it always failed for some reason with my card or my paypal, then I tried with a new credit card and it worked but the game charged me all the previous attempts as well so I got charged 4 times.
Should I revoke them on my credit card or can ■■■■■■ cancel it?

If you revoke the charge, they will ban the account.

You will have to file a email petition and wait a very long time.
