Thanks for coming back to us MrsP18, and we're sorry to hear of the issue with the O2 priority application and it's access following the requirement for account holders to link their Virgin Media accounts to the O2 accounts.
This may need to be raised directly with O2 to see if they are able to assist with the login details that you would need for your priority application.
If the account with O2 is held in your husbands name, they may need to speak to him directly as this would likely be an account holder only action.
Thanks,
