I wanted premium but got premium archive, can I be downgraded?

I recently signed up for premium to support this great service, but got two charges, one for $36 and one for $63. It looks like the second charge is the difference between premium and premium archive subscriptions, but I didn’t want the latter. I either got a brain outage at the wrong time or the payment options were a bit confusing, as I just meant to sign up for premium.

Can my account be downgraded to just premium, with a corresponding refund? Username is the same as here.

You got it, I set you up on the standard premium subscription which will renew next year. I also refunded the difference. I left your account as premium archive until then.

Superb, thank you very much for the prompt response and action!
