Suscripcion

I bought a Subscription ahead of time and it appears 0 pesos at the beginning, but when I am going to manage payments, are there these I do not understand? What I paid on the renewal day, they no longer charge me because I paid earlier? and they give me what I'm paying for my subscription

compre una suscripción antes de que acabara y me dice que tengo 0 pesos y cuando voy a administrar pago me dicen que hay esta osea me daran lo que pago mi suscripsion ese dia?
