Already have Zoho account. Not letting me log in

Already have Zoho account. Not letting me log in

I already have a Zoho account that is associated with my Google email and my phone number.

Even though I'm already logged in to Zoho, when I click on the mail icon to access my email, it takes me to the pricing page. When I click on the free option, it then takes me to another page which requires me to either enter my domain name, or else " Create email account as  <username> @zoho.com". In the field below this, it already has an username entered that I cannot change. 

Then I have to enter the captcha, which it says is invalid  - and I've tried it 6 times, and I know at least 2 of them were right.

I really want to use Zoho again, but I have never in my life had so many issues just accessing my account. Not only so many hoops to jump through, but they all lead to dead ends.

Zoho support:  What is UP with all this??????
