Edit: I did what I documented here to do, and here is the (automated) answer from the ICANN:
Dear [name],
Thank you for contacting ICANN Contractual Compliance.
Your complaint involved a domain name registered under a country code top-level domain.
Please note that ICANN has no contractual authority to address complaints involving country code top-level domainsĀ (ccTLDs), such as .us, .eu, .ac, or domain names registered under a ccTLD (e.g. example.us, example.eu, example.ac). ICANN does not accredit registrars or set policy for ccTLDs and has no contractual authority to take compliance action against ccTLD operators. For inquiries and issues involving ccTLDs, you may wish to contact the relevant ccTLD manager using the contact details atĀ https://www.iana.org/domains/root/db. This page will also help you determine which top-level domains (TLDs) are country codes (outside of ICANNĀs scope) and which ones are generic (within ICANNĀs scope).
Please note that responses to closed cases are not monitored. Therefore, if you require future assistance or have any questions regarding this case that is being closed, please emailĀ compliance@icann.org. if you have a new complaint, please submit it atĀ http://www.icann.org/resources/compliance/complaints.
ICANN is requesting your feedback on this closed complaint. Please complete this optional survey here.Ā
Sincerely,
ICANN Contractual Compliance
And the IANA being managed by the ICANN, aside from electing to use alternative DNS servers, there isn't much we can do.
