Was Gifted Game Card. Retainer Service no longer working.

I was gifted a game card. So, naturally, I punched it in! Who doesn't want two free months? Anywho, After doing so I no long have use of my Retainers which I purchased.

How do I reactivate them without losing my game card time? Going to the retainer services just adds more retainers if I attempt to purchase two. On the other hand, I don't want to change my billing stuff if I'm just going to lose the game card time. So, before I do anything... what do?

EDIT: How embarrassing. I figured it out. Seeing as I used the auto renew I never really had to encounter this manual renew thing. xD So, sorry for wasting peoples time with something so easily fixed.
