I've been very patient, but there hasn't been any communication from them in almost a week. At least some affirmation that they're working on it would help, but honestly there's really nothing to "work on" - I've never had another account.
I completely understand how frustrating it can be to be locked out of your winnings, but there is nothing more you can do at this point than to wait patiently, they will definitely get to you. There is no need for them to respond to you that they are working on it, they would rather respond with something more detailed and concerete, just give it sometime.
That said, Razer already assured holydarkness that they would address your case, so they would. IMO, there is no need to communicate with Live Chat anymore, your case has already been escalated.
