Reverb G2 no power using brick

[daronsneed]

I carefully followed the procedure to connect my new G2. Cable in to the headset, DP plug in to PC, then I used the power adapter since I do not have a USB C on my pc.  My system has NO IDEA there is a peripheral plugged in...probably because the power light is NOT on or blinking...never saw it come on for one second. I did see a YouTube video of a guy who said he had a faulty cable upon delivery. He contacted support and got a new one and it worked fine. I am thinking this might be my issue.
HOWEVER - I have tried to register my product several times and it says I either have the WRONG serial number, or that their service is down and to try later. 
Wow - I am So not impressed and about ready to go back to my lesser quality Oculus Rift S just cause it was SO much easier to use.
SO my question is: how do I actually reach customer support? And where is the "serial number" for my device....it's amazing how hard HP makes it to service we the people that gave them our money.   ugh

Hello there, the serial number is really small and faint (god knows why)! Look all over the box, what I did is I took a photo of the tiny label and was able to make out the number. The serial number begins with 8CC. Don’t worry you will find it👍🏻
