I have to refund it, but my application has not been submitted

I didn’t use Sketchup, but I forgot to cancel my subscription, so I paid for it. The payment was made today, November 25th, and I would like to request a refund. I want to submit the form as shown on the homepage, but the submit button won’t press…
I’m a foreigner, so I’m not good at English, and there’s no way if I can’t submit it on the website. I’m so lost and worried. Please help me.

Did you buy the subscription via a local reseller?
If so, you best contact them directly…
