Actually there is something else you can do. Go down to the local PD and file a police report, at minimum the crime is theft and if they want to pursue it the crime is fraud. They advertised a new product and sold you you new one.
Get a copy of the police report and take it to the manager, ask them how far they want to take this, because you're ready to go all the way.
As to your word against thiers? Actually it's not, it's easy to verify that you don't have an active code on your account. I'd also be willing to bet it's possible to verify that you tried to enter a code and WHEN the code was attempted to be entered which also backs up your account.
Additionally feel free to contact the Better Business Bureau. Again if you want your shit back you can get it, you just have to be a real PITA.
