Did Umbrella Labs just scam me?

I made a $400 order with umbrella labs 3 days ago. I have not received any confirmation that my order has been shipped.

I’ve tried emailing support and received no answer, I tried calling their support, no answer.

What is going on? Should I cancel the card I used to pay for it? This is the . IS site.

Update: my items shipped, three weeks later. So not a scam just very slow.
