Platinum Brazilian

We are Brazilians will not have opportunities to buy platinum in arcane legends? Why is not anyone who has international card at least here in my city, and from what I know only have to buy platinum if someone by the data in the cell, in which case I play on mobile ..
I want so much for platinum, but do not have that privilege ..

Thanks for understanding

Can you purchase a game card? Like Google play or iTunes card?

Google wallet is supported in Brazil. Try them.
However i feel Paypal should be supported in AL
