Hello, I purchased Guitar Hero Live - 2 guitar bundle. One of the usb receivers is broken out of the box. I have tried following the steps from another post advising to go to the Warranty page and fill out the information. As soon as I try to put in usb receivers (under Other Hardware), i get redirected to a new page that says "The Site Hit a Brick Wall" - I've tried 2 different browsers with no luck. I've tried the Contact Us link. I go through the steps and only ever see that Activision Chat isn't available right now - it's been like that since 8am Eastern today...it's now 12pm. Please help me get some support.
