Help with canceling a subscription

Hey guys, I play this game on and off and noticed I am being charged 9.99/month for the Hunter Association Premium Subscription. I didnt realize I signed up for it but I wouldn't doubt it either. Anyways, I cannot find any information on this subscription accept for purchase history over the last few months. Saying I am being charged 9.99 every month. There are no active subscriptions in my Google play account for it. Absolutely no recent purchase shown in my net Marble account. And my PayPal doesnt show it as a subscription but in stead shows it as individual purchases on the same day every month. It looks like Inhave the ticket to do the special summon though, but I cant find any purchase history from net marble or active subscriptions anywhere to cancel. Does anybody know what I'm missing?
