Unable to see any accounts on MY BT

I log in to my BT to see my bill and to claim the Xbox game pass and I get the following message and no accounts show.

Sorry, we can’t get your account details at the moment

We couldn’t find any account details for that BT ID. Please try again

Hi @Stewieb2580, sorry you can't access your account online. 
Are you using a BTID that has been previously used for an old account?
Cheers

John
