Unsatisfied customer

My husband works in Nigeria on a fixed contract and only comes home twice a year. He gave me full authority on his FNB profile years ago to handle all our financial matters. When he did this, he also double checked with the staff member that I was the only person with authority and this person confirmed it. He also ensured that all details were changed to the correct cell nr's and email. Recently a 3rd party contacted me to enquire why she was still receiving all his financial emails and that she still had signing authority. Very shocked I rushed down to the Tygervalley branch to remove her and to ensure that all details were corrected. The consultant was very helpful, however, the lady that clarified a question for her, did not even greet me. I must say, I felt uncomfortable. Anyway, I was ensured that everything was rectified and on my way I went. I was just informed that this UNAUTHORISED person is STILL receiving emails on my husband's account!
