Urgent----anybody know Hipaa...that covers patient record rights?

I am seeking legal aid for my mother so I retrieved all of her records from the hospital today, went to patient advocate and asked her to show me where to find in this pile of papers the two complaints I filed with you verbally...she stuttered and said that is not patients right to see those records...I am to tired to fite and I pad went dead so I will call her in a bit to ask her to repeat what the rule was cuz I am confused I don't understand why that would not be part of the file. when we spoke on phone it was my main request. complete files including complaint and follow thru actions....she sed she would get em for me and now...that is not my right??? these guys are pissin me off something fierce...I need It and I need it now!
