Incorrect details and misinformed

I added my child on my funeral policy last year on 22/02/2017, no documents were mailed to me this year on 09/02/2018 I called in t request documents and to my surprise the details of my daughter was incorrect. I then decided to call in to have the error rectified spoke to Christopher Madinga who advised me that I am unable to update her details without the child full ID as the date of birth will only pull through any child born on the day, I then posed a question to him of why was I not advised on the day that I added my child of the importantd of full ID he was not able to answer but rather told me that the sales consultant who assisted me must have told me( Verosha Behari) if something had happened to my child apparently recordings would have been requested and we know how those take, I have many accounts with ABSA its time I cut ties because what if the unthinkable had happened? would I have time to call in and query? how can you request full ID number whereby your own policy documents only states dependents date of birth??
