It might be a publisher who have implemented our system incorrectly, however we take this very serious, as our #1 guarantee is that our codes WORK every time.
Please understand that we only are offering unlocking codes and thus we're not directly responsible for the content provided by our publishers as long as the codes themselves work.
Our general guideline is that every partner must provide what is promised, however as we're only responsible for the unlocking codes, it'd be better if you contacted the third party site directly in order to receive your content.
If you've purchased a code then keep in mind that we only refund payments in the situation that we were unable to deliver the code due to technical issues. Thus, in this case, you are not eligible for a refund.
