Need to remove subdomain permantly

Hello,

I previously deleted my account and subdomain (auto48softcactus.wuaze.com). However, DNS checkers show that the subdomain is still resolving to IP 185.27.134.24.

My organization requires this URL to be completely removed from the DNS records so it returns a ‘Domain Not Found’ error. Can you please manually remove the DNS A-record for this subdomain from your nameservers?

Thank you.
