Premium monthly to annual and familiar (COLOMBIA)

[MigAngAgu]

Hello, 

Since my country's help page (Colombia) send me here, i will post here.

I'm a premium user, with monthly payment, but i would like to change my suscription from monthly to annual, and would like to get the familiar plan, but i could not have find the right information about the fee. I found the Annual suscription fee, and the familiar monthly fee; but not an Annual Familiar Suscription plan/fee.

Does anybody can help me? Hope i was clear.

Thnks!
