About 10 years ago, I registered two domain names with BT. One (.com), has been pointed at my externally hosted website for most of that time. This week, my hosting company was bought out, and they transfered the sites to a new server, meaning I need to redirect my domain. However, when I log into my BT Business account, it shows no domains registered. A whois lookup shows the domain in question has register.com as the registrar, and I believe they are BT's partner for domain registration.
Is there a reason I can't see either of the domains I hold with BT in my account?
