Serious Issue Security Internet Banking

I have mailed my private banker on three occasions indicating there are issues with my account. Firstly, when I log on to the internet banking, I do not receive an SMS. Secondly, when money is tranferred between accounts there is no notification as well.<br> I have had a debit and a credit on my account with no explanation as to why this happened without any authorization. I have emailed my banker constantly requiring feedback since last week and week before when the first issues became apparent.<br> I have closed my Business Account with Standard Bank a year ago and moved to FNB because of similar issues which Bank Manager of Richards Bay could have cared less about. I retained my personal Private Banking account for convenience sake. But I I will be left with no option but to move my account to FNB if this problem is not resolved. I, as a Private Bamking client should not be resorting to these platforms to resolve this security issue on my account!!
