Can't reach support - Suggestions?

Bought the new Razer Blade Steath... USB-C port stopped working a few weeks later. Spent forever dealing with RTazer's horrible chat support only to have them say I need to send it back. Finally get an email with a FedEx shipping label and a confirmation that FedEx will pick it up on Monday, July 20. So I pack it up, label on, and handoff to the FedEx rep who scans it. Then got an email a few days later from Razer saying they have no record of the package (laptop) being picked up. So the laptop is in an abyss, and I can not get ashold of ANYONE at Razer. They haven't responded to my ticket, they don't answer the phone, and I can't access chat without the serial number (Yes, I should have written it down but I didn't). Any suggestions? Really pissed I paid extra for the expanded warranty coverage, and have this horrible customer service for a +$2,000 LAPTOP.
