How to get support on a trial licence issue?

I'm a non-corporate user with a Tosca trial-license issue and I can't find a way to reach support.

Background: I finished AS1 and AS2 and started the TDS1 course a few months ago, but when I wanted to continue today Tosca Commander could no longer load a valid license from the cloud license server.

Attempt 1: I checked under https://support-hub.tricentis.com/open?id=training_license_request and it shows two training license requests with state ‘Deployed’ with the latest updated on "2026-05-14” and the [Request Cloud Training License]  button is greyed out with the tooltip “User already requested too many training license requests”. (There is no delete button or any other option either.)

Attempt 2: So I sent an email. Got an email back saying "we have discontinued the option to open Academy cases (former: incidents) via e-mail. Please log into the Tricentis Support Hub and connect with the Virtual Agent to find a solution” Fine.

Attempt 3: I go to the support hub, find the virtual agent and it says "You do not have the necessary rights to start this chat. Make sure that your account is linked to your company account”. (I'm currenlty not working for a company that I can register and this should not be necessary for training licenses.)

Attempt 4: I called the support line. I'm asked for a support ticket number or to press 2 if I don't have a support ticket. I press 2. I get an automated message directing me back tot he support hub, no other options.

There should be a way to contact support for users like me but it now seems completely blocked off?
This is attempt 5 hopefully somone here knows where the support option has been moved to?
