Trans Union don't make your $15 mil demand our problem when you mess up.

I need to log a dispute with them and all they need is my ID number. Now they require me to register with them with my personal details - who can trust them when they have their data ******? So I register and must have a minimum of 12 digits as a password probably for security reasons (and their data still gets hacked). Now it has locked me out because of something I have done wrong in their complicated system - and I am computer literate. Next I must call them at my cost to unlock my account for a mess they are making with my credit score. There is no simple email to write to visible on their website. I tried calling earlier and after holding for 5 minutes I just gave up. Unbelievable.
