No Mobile Access After Annual Subscription Paid

Paid in full only to have my access and all users access denied to the mobile app. Getting the message "trial has expired purchase the professional addition for access" WHAT? (3) email attempts to zoho support and also its team members who were quick to have me sign up for a paid subscription. ABSOLUTELY no response not even and acknowledgement of my of my email. 2 phone calls to support only to get an answering service. WHY would i leave a message to a company who doesn't respond to begin with. This is not how i expected it to be. As it is i'm effectively shut down with my app with which we've successfully implemented into the field for the last couple of weeks. THANKS FOR NOTHING. I want a refund!
