Re: how do I contact ea's customer support?

Again... this is the WRONG FORUM.

Plus, the AHQ is for player-to-player self-help and technical discussions.  No one here can help with accounts, entitlements, purchases, or refunds. For all of those you need to be talking to the EA Game Advisors at help.ea.com.  That is, simply, THE ONLY WAY to get assistance with those sorts of problems.
