Sites down, Plesk Panel Down, Live Chat down (whatsup?)

My Sites are down because: 1. Your Windows Plesk hosting environment is down 2. My Let's Encrypt Certificate that was supposed to auto-renew didn't

Now I cannot get to my site, or log into the winsvrweb07 Plesk panel to fix the certs.

I've been trying since this morning to get help on your "Live Chat", but it is dead, and no one is replying on the Business WhatsApp line.

I've also logged ticket #*** which has received no attention.
