Unable to turn off scam protection

[Janes2]

I have read the various posts about turning off scam protection which all use My Account. Unfortunately I am unable to register for My Account as after entering email and account number, i get the message:

Unfortunately, we are unable to proceed further due to insufficient information on the account. Please contact us for help.

The 'contact us' link doesn't help either. I need to speak to someone about this but am unable to do so. All the telephone numbers I have eventually just end up with 'we have had to close down this line'. Please can someone help?

Hi Jane, 

This means we do not have a mobile number for you linked with your account, Can you please update your community profile to include your:

• Name
• Telephone number
• Alternative contact number

We'll then look into this further. Please do not post this information on this thread. Once you've updated your profile please post in your topic to confirm it's updated. 

I've also sent you some security question via private message i need you to answer. 

Thanks
