Good Morning TrevHadfield
Thanks for your post and I'm sorry to see that you've been having issues with your account.
We wouldn't be able to change the primary E-Mail address, however we would be able to change the password on your account to allow you to access the self-care account and you can then make the change to allow a secondary E-Mail account to be the address you use to log into the self-care account.
Have you been able to try and change the password on the self-care account/primary E-Mail address to gain access and get the PIN number?
Do please let us know if you need any assistance and either I or one of my colleagues will be happy to help you via our PM service
Kindest regards,
David
