Account area broken, cant manage static ip or services

[#1]

Could someone take a look at my account. When I go to manage my static IP i get this:

If you are an existing customer
Unfortunately, this feature is not available with your current account. To raise any queries and to upgrade your account, please use the Contact Us tool here at the Portal

If you have recently joined PlusNet
It may take up to 30 minutes until you can access this feature of your account. Please try again later. Go back

If I go to to the main broadband page I always have an error at the top of it:

An error has occurred
You can't change your products for the moment, you have an order which is currently being processed. Please try again later.

It's been like this for months, I want to go in and update my hostname.

Thanks

Same for me, But I think you need a business account for that page to be working,
Check the "Add-ons" tab to set static IP

These pages apply the same to both residential and business users.  I have a fixed IP address and cannot access that page either.

DNS settings are managed somewhere else in the portal - see Manage account -> Manage your domains
