Membership, paying more in advance

[Elahhez]

Hey people

I have an usual situation here.

I subbed for membership in planetside2 for 3 months. Now have a 35% bonus from that until sometime next year. But i would like to pay for an additional 3 months before that is due (like in the next days), to get the higher bonus faster.

Now.. What is the best way of doing that? Do i cancel recurring charges, then can add new payment, or does that null my 3 months paid i already paid, or what you guys reckon is my options?

I hope my question is clear.
