Hello @MiHiHemi
Thanks for posting here in the Community.
We would recommend you try to restart your router and then see if you will be able to access our website. You can also try using a private or incognito tab. For reference, you can contact them here and then choose Accounts, payments & subscriptions. They are the best ones to help you with double billing.
Let us know how it goes!
All the best,
