I'm trying to delete a credit card and use a new one.

 

I get this message: Please change your payment option for these subscriptions by contacting support before removing payment option

 

How do I contact support?

The old credit card has expired, I am trying to change to direct debit.  I have added the direct debit details but am unsure how to make this the primary payment method.  When I attempt to delete my credit card the warning advises 'The subscriptions listed below are associated with MasterCard xxxxxxxx. Please select another payment option to use for your subscriptions before you remove payment option MasterCard xxxxxxx'

But when I reenter my bank account details under this function the system advises the payment details already exist.  Can anyone help?
