Payment to get a Premium account


I just can’t understand how can I pay to buy credits.

I’m from Brazil and this micropayment system says I hace to deposit in their account but I don’t know how to do it from here.

I can’t find anything related to paying by credit card or pay pal, or any tool I’m used to work with.

Could anyone help me or explain me how to do it ?

Thank you very much!

You most likely picked a package size of 50 Credits. Due to high fees, Paypal and Credits Card are only available from 100 Credits and above, though.
