Aside reaching them via emails, being able to set up a responsive customer care service who could be a member of the forum should also be provided so that when customers are not able to get quick answers through emails they can drop a message or complain in their telegram or other social media handles. We need to get a response from the team to enable us know the next things to do when asked about the various ways to reach them to get their services. Since KeychainX has been in existence since 2017 according to the op we ought to have gotten the various ways people can reach them, the explanation of their terms of service and their records when it comes to wallet recovery. Let there be a good response from the team we need response.
I think the customer care should be active on almost all the social media and platforms they are operating. Like for example, the forum is one good place, telegram, reddit and any other platforms you can find people who needs their services. Recovering service is a very sensitive one. No one would feel safe knowing their device and access to their funds in Bitcoin are with someone else without thinking about it. So if they dont receive quick response from members of the team they will worry a lot.
