That's your problem then because the cartel pack stock photo shows it's obviously incorrect. A bit of logic would tell you that it not reflecting what was in the stock photo was false advertising if they left it as is.
I disagree. Going off preview window would be the logical way to check vs the photo on the pack as the preview window shows what it will look like on your character. They need to learn that if they mess up a paid item they need to make changing it optional or offer refunds to people who don't want it after the change. If you didn't get what you paid for, or it was changed to something else after you received it and they refuse to refund your money (or at least the coins) go to the Better Business Bureau and file a complaint.
