Transfer your domain to a major registrar. Tierra.net looks like some bs cheap registrar and doesn't have any social media updates on their accounts since 2017. I'd recommend Namecheap.
If you do whois lookups against the top 50 websites you'll see a lot of them use a small set of registrar's. But not all of them accept small businesses.
I almost has a domain frozen with namecheap after one warning. If I missed the warning email or checked my email after 24 hours they would have completely suspended my domain. I'm talking about a site with MILLIONS of visitors per month and ten thousands of posts per day, not some small blog.
Spoke with lawyers and from what i was told in consultations there's basically nothing I can do about it.
TL;DR Namecheap will endanger your family and they give 0 fucks.
