Why is my account disabled?

Why is my account disabled?

I'm a new customer to Zoho and so far I've had a bad experience! I signed up using my own domain and want to set up email.

If I click 'access Zoho email' from top right of window when logged in, I see big yellow triangle and account not active text.

If I try to login to  https://www.zoho.com/mail/login.html I see 'account disabled' warning.

WHY?

I've emailed Support and had no reply. I've tweeted @zohocares and I posted in another topic in this forum 2 days ago. 

Can someone help? I just want to set up email.... :-(
