You either made this up, or talked to an idiot.
I work for EA. Let me just say that I don't work for Bioware, nor do I have any connection to the dev team directly.
I do, however, work in a department that gives support for Origin.
Here is the truth:
When you ordered your copy of the game, digital download, you found two items in your order list. One was the game, at least 54.99. Under that would be a 5.00 pre-order charge.
You were billed for the 59.99 (or higher depending on which version of the game you ordered). Then, 54.99 of that was released back to your charge card.
The 5.00 pre-prder fee was kept, securing your copy of the game.
At this time, you were sent an email comfirming your order. In that email was an invoice for your order, and it contained the following:
Product SKU: 71065
Product Name: Star Wars™: The Old Republic™ Digital Standard Edition Pre-Order Fee
Qty Ordered: 1
Amount: $5.00
Serial Number: BLAH-BLAH-CODE-GOES-HERE
Notice the product code is listed UNDER the "Pre-Order Fee"? That is your early access code that also rewards your account any pre-order items you would recieve.
If you didn't get this code, you won't get Early Access, but you also won't get any Pre-Order items you are supposed to get.
If you didn't get this code, contact Origin immediately to get it.
You enter that code on the swtor.com website, and you are all set for Early Access.
Actual product codes will be emailed to you when the software is "released" to the public. That date is expected to be the 16th, but some may not get their product code on the 16th.
Of course, the charge of 54.99 has to clear before you will recieve your Product serial number.
Once you get that email, with the product serial number, you come back to swtor.com and enter it in under your account details. You will be good to go at launch, 12:01 am CST December 20th.
Do you happen to know the name of the person you talked to that told you differently? I'd sure like to pass it on to senior management that someone is lying to customers.
Unless, of course, you are making this up. You can take what I said for fact.
Hope that clears up your doubts.
Cheers.
