How to receive the 30 day free trial after I skipped this step?

[Tour South Africa]

I am a Virtual Assistant and I have created a Trello Account for one of my clients.

It gave me the option for a 30-day free trial for Trello Premium if I added my client's card details. I didn't have her details at that moment so I skipped the step.

She has given me the details but if I choose Upgrade, it now only gives the option for a 14-day trial. How can I get the 30-day trial?

30-day trial is only when you create a new account. Existing users receive a 14-day free trial.
