Going round in circles a bit so any advice welcome. I am helping a client that believes they own a .com registered 10+ years ago. The WHOIS states their business name, but all other info private. The people who would have registered left the company years ago and not contactable. The registrar has said the domain was registered through a reseller, who in turn have passed us to another company, who has a history of M&A and suggested we speak to GTT.net, who don't believe they can help us. So in short, no one is taking responisibility. We have no legacy invoices, references etc. Going back to basics, should the registrar stated on WHOIS be able to help, or do we need to keep probing? Like Nominet, is there a central registry process to regain access? I've not done much in the .com space aside from registering.
