As you have edited your posting now.
My advice from before still applies. Try to contact them and buy the domain from them.
If a domain is important you should never let it expire, but how does the saying go about spilled milk.
Anyhow, assuming that you are talking about
halnwood.com it would appear as if that domain was registered a couple of days ago in Europe. As you seem to be based in India you most likely won’t be able to invoke local law in that case and would succeed with a trademark complaint only if you have an internationally recognised trademark (if you have one at all).
At this point they are the legal owner of that domain - as I mentioned before - and “complaining” to the registrar or Cloudflare won’t do much as they are not doing anything illegal.
Your best bet is to seek legal advice and check what options you have. I am afraid neither Cloudflare nor the community here can do anything.
