Bought game on Steam but says code has already been used

I bought NFS unleashed shift 2 and for a year or so never tried to join the online part of the game.  When I tried recently it said that my product code was already associated with an account.  Well, either I need to be given the access to that account or a new product code or my money back.

The fact that EA actually does not have any real way to contact someone is just a wonder.  I doubt I will buy any more of their games, and I have bought quite a few in the past.  But I hate to be give the run-around.  That's why I pay three times more than att charges for internet, because they have no service or customer support that isn't an insult to their customers.  You seem the same.
