Help creating a new account?

I have just subscribed to the Starter 1 year license, my credit card was charged but can’t use the product because the system does not let me create an account.
When I enter my email address (same as I use for the payment), phone number and password I get the following message “Oops Something went wrong. Please try again and if still doesn’t work, let us know”.
When I click on the link to let them know I get the following message “Access to www.quicken.com was denied”
Any advice?
In addition the website advertises a discount of 10% for new members and my credit card was charged the full amount.
Frustrating, I couldn’t even see how the product works and I would like already to quit and ask for a refund.
