domain.com NO GO for serious business

<p>I bought my domain and email address from Domain.com My Business has suffereed badly since the email </p> <p>servive has gone down. Despite sceveral attempts to understand the problem, DOMAIN.COM continue to </p> <p>say they are escalating the problem to yet another supervisor, then a senior supervisor, and no word. </p> <p>Perhaps there is no one qualified to deal with a problem such as email going down ????? with a company as large as DOMAIN.COM, that is odd, or perhaps they don't really care once they have your domain registration and email fee. Terrible supprt service</p>
