If you want to buy cartel coins with this issue your only chance is buying an EA cash card and reclaim it.
Sounds like a valid work-around for folks having problems buying directly.
Should work-arounds be necessary in life? NO. Are they a fact of life? YES. Why? Because the world is imperfect, so life presents us with challenges to overcome.
Seems to me.....anyone who really enjoys the game and has an issue of any form.. they would find a work-around that works for them.. and proceed to play the game they enjoy.
