WTF!? I HAVE to pay for second month after buying?

WTF is this? Maybe I just want to buy the account/game and try it for one month and if I don't like it then I won't pay for a second? Is this possible in any way? I only have 50$ left on my card and I don't want to pay for a second month yet anyways. Are these guys serious, or can I change my card number after I buy a new one and pay for the second month if I decide I like it or even cancel my subscription if I go out and get a new 100$ card?

Greetings,

The subscription will renew each month and bill your account. However if you wish to not subscribe anymore or simply want to take month out, then you can cancel your subscription.
If you are unable to cancel your subscription then please contact support using the Link titled 'Support' at the top of the forums, and they will be able to cancel it for you.
Hope this clears it up for you.

Alright thanks.
