I sent my Rift unit for RMA due to a defective tilt sensor. I noticed after the return shipping tracking number was provided that they had my old address listed despite my providing and confirming an updated address multiple times. It has been more than one week since I raised the issue and customer service has not responded to my requests to correct the address/contact UPS over the support ticket. Of course, there's no number to call to speak with a human either. Any ideas on how to correct this?
