Problems changing nameservers to transfer out
I am trying to transfer out 2 domains. I updated the contact info, unlocked the domains and have received the authorization codes and attempted to change the nameservers on Friday night/Saturday morning. Today is Tuesday evening and one domain says it is in the transfer process and has the correct new nameservers. The other one shows as disconnected on the new hosting site and when I check the nameservers, they are still the old homestead ones. I have repeatedly tried to go in and correct them to the new ones, but each time I hit submit, the old nameservers show up. It says it may take 48 hours to update changes, but it has been 48 hours and the other domain has not had any problems yet. Please help.
