Breach of privacy

I have been a member of Nedbank for more than 12 years and recently got a joint bond with my wife (who is not a nedbank client). I understand as the main applicant that the bond statement comes to her, but MY investment & other statements should NOT go to her...I still have to have my privacy...all my statements go to her, which we never signed for and i did call your call centre and apparently "it was resolved", but my wife is still receiving MY statements and not the bonds only. My wife should ONLY receive OUR bond statemens and NOT MY personal investment, we did NOT give that permission. please fix this nonsense as in yesterday
