Absolute garbage support. Dont know anything about nameserver registration process when same domain is used. For example, when setting ns1.example.com nameserver for example.com domain, the nameserver must be registered first before using it. Otherwise it will not show any DNS records. This is called glue record. Instead, the support added an A record in bluehost(not using bluehost nameservers) and set custom nameservers. DNS zone in the server was already ready in the VPS. All they had to do was register the nameservers. UI glitches all across. Changed nameservers and re-logged in to account because dns never propagated. Saw the old nameservers. Updated it again and waited. Re-logged in and still old record popped up
