If it's your first time loading up, it will take several working-days in order for it to be 'approved'.
Also depends on what you bought it with, could take 3-5 working days.

If it's not your first time, and you bought it via whatever that doesn't involve old-fashioned bank-transfer, then your best bet is to write a ticket via SUPPORT (see button on top of your screen).

Also, I have no idea what I'm talking about, just jumping in from time to time to see what didn't change.
