Bogus email from Plusnet - Please update your payment details - Plusnet

Have just received this email twice from support@plus.net.
...
We don't have any valid payment details saved for your account. You can add a card
or Direct Debit details by going to My Account:
https://portal.plus.net/my.html?action=update_credit_card
Note: If we can't take payment we may apply restrictions to your service.
...
When I go to my account and check, the direct debit details are there.
What is happening?
