Subscription "recurring" payment problems

Hi! I need help with something related to subscription payment.
The other day i bought crysta so i could buy 1 month of gametime. Everything was fine until yesterday when i recieved a bank message telling me that my card was charged again for the same amount i payed for the crysta. Then i checked on the mogstation and noticed there was that pesky "recurring" payment activated again.

I'm not an expert but as far as i know "recurring" payment only applies when you pay directly from a debit/credit card, am i correct? then why is this happenning again if i'm buying the exact amount of crysta for just one month? I don't get it. How can i get rid of this issue?
Any help would be greatly apprecciated! :D

PD: Happy new year everyone!

Have you always used crysta or have you used a bank/credit card prior to that? If so when you use a time card and use a CC before it revert to recurring CC payments unless you tell it not to. I would imagine this might be the same setup for crysta. Also did it use your crysta or still available to use?
