Why doesn't Razer Support Respond? Why is there no Warranty? Why is a 300.00 Keyboard a useless POS?

In January I bought a Razer BlackWiddow V4 Pro keyboard, I opened a ticket about an issue and that was resolved.

I didn’t think anything of it, but as time went on, the double key press started happening on several keys. At first, I thought it was me, I gaslighted myself to say that maybe my fingers were twitching.

I tried to open a support claim, but the keyboard serial number is worn off (note, no scratches or anything, just rubbed off like it’s a cheap ink on top of the sticker. 

I tried to open a support ticket based on my old one to get the serial number, no replies. No support. Nothing.

So my questions to the community

1. Why doesn’t Razer support respond?
2. Why does my $300.00 keyboard apparently have no warranty or support?
3. And WTF is wrong with the switches? Note, Amazon has a flood of reviews with the same issue, you can now see several youtube videos demonstrating this issue.
4.
