Subscription portal not working

I’ve been trying since Monday to access the subscription portal to cancel auto-renewal, but every time I try it looks like this:

The unsubscribe button doesn’t work, and all the different subscription options are just in one long page, when it looks like it’s supposed to be divided into tabs. I haven’t been able to cancel my subscription. I contacted support on Monday, and they assured me that auto-renewal was cancelled already, but today I was charged anyway. I can’t even get a refund since that’s on the same broken page. Please fix this.

For best results from this forum, I suggest you add any screenshots/phots etc direct to your post by simply clicking the link “Attachments and other options” which can be found below the text box.
Several people on the forum are weary of clicking 3rd party web links to view photos.

Sorry, this interface makes it kind of hard to tell if the attachment is going to post or not, so I went with something I knew would work.

No problem accessing my.avast.com here.
Did you use the following link? https://subscriptions.avast.com/
If you have a problem with cancellation try the following:

If you don’t have an order # use 00000000 then explain your problem.

https://subscriptions.avast.com/ says I have no licenses, even though I do. All the emails I’ve received about my subscription linked to this subscription portal as the way to manage my subscriptions, and it’s also the page that’s linked in the FAQ here for people using Digital River payments. I have contacted support twice, and received a refund, but since support informed me once before that my subscription wasn’t set up to auto-renew and then it did anyway, I’d really like to be able to check for myself.
