Hello Niamh_winstone,
Welcome to the Community and thanks for taking the time to post here on the forums. I’m sorry to hear of the issues that you’re having with your password reset for your online account. Just to let you know, the password needed to call through to the team is your memorable word/Telephone password not your online account password, also if you get the information wrong you will be passed through to an agent.
I'd be happy to take a further look into this for you but first I would need to confirm a few details via private message, please look out for my message and we can get started.
Kind Regards,
Steven_L
