Restore Domain and Website Access

My website hosted on Hostinger is currently unreachable because the domain appears to have lapsed. I already attempted to renew it myself but wasn’t successful, and the registrar isn’t responding to emails or providing a phone number. I need someone who can quickly step in, diagnose the exact domain status, and get the site live again.

What I’m looking for:
• Verify the domain’s current state through WHOIS or the registrar’s control panel.
• Liaise with the provider on my behalf—handle emails, support tickets, or alternative contact channels—until the renewal is processed (or advise on transferring the domain if that proves faster).
• Reconnect the renewed domain to my Hostinger hosting, update DNS records if needed, and confirm propagation.
• Test and confirm the website loads correctly from multiple locations.

Please outline your plan and estimated timeline. Experience with domain recovery, DNS management, and Hostinger is highly valued.
