Monthly Subscription Payment Issue

Okay so my question is the following. I've used prepaid cards to buy gametime until last month that I decided to use my credit card. Today, 5 days remaining for the end of my purchased gametime I received a mail saying that there is an upcoming payment on march 14, when my purchased gametime (with credit card) ends. Does that mean that the account will automatically take money from my credit card to let me continue playing? Or does it give you the option to renew yourself, and if you don't, you can just say no? I decided to buy a prepaid card again due to personal reasons so I would be very displeased if I were to be forced to pay an extra month with my credit card on top of the 2 months I've already purchased. And if it doesn't give me the option of whether I want to renew or not, can I somehow cancel this automatic process?

It's an automatic renew of your sub, you bought an abo.
If you wish to go back to manual sub (prepaid card) you have to cancel the automatic payment via credit card.
