About customer support, you use this page:
Support.
You can do it all from there. A warning, though: EA has a bad Customer Support centre. I sent them an email months ago, and I still haven't receieved a reply.
If you can find a phone number for the Netherlands (I couldn't find one for America, at plain sight), I would say call them, don't email - then you can guarantee you get a reply.
Side note: I went the extra mile for this. I had to have both my username and my password resent to me.
EDIT: And I didn't mean to bash EA, so I'm really sorry if it comes across that way.
