Disclosed personal statement to a 3rd party

In December we moved from KZN to PE. I went into the Walmer branch to sort something on my account and was asked there, to change my branch to Walmer (previously Stanger). Did so, and added my wife as secondary user on my account. Natalie promised me to switch the debit order, however didn't. The debit orders bounced and she gave me a trail of sad excuses and delayed coming back to me as my prestige banker! She promised my wife a gift for opening up her new account - NOTHING CAME! we had to go in a few time and spend hours in queues in this so called prestige area - what a waste of my time and money! I sent her an e-mail 2 months ago to change the cell number for the one time password for my wife's account - still awaiting a courtesy reply back! Called in to complain yesterday, she added a postal address to my wife's account which we did not authorize. Now - somebody had a access to our personal statements, and I will be taking legal action against her and the branch! I sent her an e-mail yesterday to ask her about this, and I asked the call centre to send her manager a message to call me regarding this nothing! Standard bank Walmer is disgraceful and needs a new set of employees
