We found one or more linked accounts

Hi,

I'm trying to sign into my EA Account on the EA Desktop, but I keep getting the following message:

We found one or more linked accounts
The EA Account is already linked to the following Xbox account(s):

• (MyXboxID)

You can switch your Xbox account or continue with a different EA Account. For more info, visit help.ea.com.

I'm using the credentials I'm using to sign in here, and it shows in my linked account...but I show two Xbox accounts linked, my genuine gamertag, and one I had about 2years ago test...somehow it's also linked, and it seems to be blocking my ability to sign into EA Desktop. I've gone through the steps listed in EA's documentation to unlink accounts, but there is no "unlink" button on my browser under the Connected Accounts tab, tried on a couple of different browsers...has the process to unlink changed? I just want to be rid of the old account so only my actual gamertag is linked. Anyone else having this issue?

I don't know how to contact EA's technical support team.

Any help would be greatly appreciated!
