Let´s Encrypt certificate used for phishing domain name, what to do?

Help
1

Not my domain, domain name used for phishing: deutschepost-tracking.de:
This domain has a valid letsencrypt certificate and is used for phishing.
I received an SMS with the link to this website and and parcel tracking number

When visiting this website in a sanitized browser, it looks identical to the official website, asks for customer information then a page for payment with credit card.

What to do ?

OK I get the point.

So, I notified safebrowsing.google.com about this website / domain
There is not much else to do if I get it right.

Here is WHOIS Service for the domain name deutschepost-tracking.de; that may help as a starting point for filling reports and stopping them.

This yields the following contact form to submit a complaint (I don't know if the registrar is DENIC and they'll investigate the complaint directly, or if only the registry is DENIC and they'll forward the complaint to the registrar).
