Unable to Manage ("Remove") Devices on Xbox Music Account

I just traded in my WP Lumia for a replacement handset. I'm full up on the number of devices on my Xbox Music account and need to delete / remove older devices from the account, but when I go through the process it's failing every time. What do I need
to do to get the old phones removed permanently (since the documented process isn't working and the devices are still showing up under the account).

To remove a computer or device from your Music Pass

Open your account. (For information about how to do this, see the “View devices that are associated with your Xbox Music Pass” section.) Then, click Remove next to the name of the computer or device.

To add a Windows 8 computer or tablet to your Xbox Music Pass

Download an Xbox Music Pass item from the Xbox Music Store to your computer. It will be added automatically.

To add a Windows Phone to your Xbox Music Pass

Sync an Xbox Music Pass item you downloaded from Xbox Music Store to your device. It will be added automatically.

 

I can't remove a device from my account either. It re-appears after I delete it from the account. This is stopping me from adding my new device to my account because I am at the max.

Can this limit for devices be suspended (or at least allow us to add one more device) until this problem is resolved?

 

I am also having this same exact issue. Waiting to chat to a support agent right now. Will update if I get an answer.

 

The chat support agent just removed them for me. Left the chat before I could find out why I couldn't remove them myself

 

I am having the same trouble. Please Microsoft WP Lumia Xbox music......HELP
