Unable to access live support chat

It's my understanding that posts like this are allowed, but if not please feel free to delete this and I'll repost in the support thread.

I'm trying to contact Razer support regarding an RMA claim but am unable to access the live chat. The button is greyed out and unclickable, no matter what browser/device/internet connection I use. I'm hard of hearing so I'd prefer not to have to call the support line.

I just received my new Core X V2 and am fairly sure I got a defective unit as I haven't been able to get it working despite extensive troubleshooting. I can't get it to power on at all beyond a quick spin of the fan when turning the PSU on and off - not even any lights. I've tried with multiple PSUs, am sure the GPU is good, and have unplugged and replugged everything to no avail.

Hoping this gets seen by Razer support or someone is able to direct me to another way to access the chat. Or maybe there's a support email? Thanks in advance.
