Can't Access Report

I have been trying to log onto my profile since November last year. Called the call centre to say that I have been logged out due to too many attempted logins, even though I used the correct password and login (I wrote it down in my diary so I did not forget). Got through to the centre eventually after 10+ minutes. We went through the security check questions until the address that they have for me on the system, which has been the same since I was born and has not changed until the last 2 years, I gave them both addresses and they told me I am wrong... how can I be wrong??? Those are the ONLY addresses I have EVER lived at. They gave me an address for "webadmin", told me I need to send my latest proof of address and ID, which I did, on the 17th of January - I have since called into the call centre twice (the operator elevated my complaint), and I have emailed another 3 or 4 times and I have not heard back from anyone. This is now breaching my personal right to my own private information. I want to access my report and I can't and no one has got back to me.
