Consumer protection? What's that?

Once upon a time, I co-owned a house with my ex. It was not a fairy tale and eventually after 18 months of agony with Standard bank (check your records at Bayside branch you will see what I mean) I finally managed to rebuy my own house. This house has been in my own name in payment and in account since that day. The only mass irritation I had since then has been that Standard Bank Insurance is incapable of taking my ex's name from their household insurance coverage docs, so I send an email once a year complaining - to which i never get a response. However, that document is sent to me and me alone, so whatever. However - my ex contacted me through a 3rd party (it was an incredibly bad split) to advise that Std Bank has sent my HOMELOAN ACCOUNT through to my EX via email! <br> Point 1 - HOW DARE YOU share my confidential information with a 3rd party?<br> Point 2 - My instruction to you was to post my homeloan statements, which you have up to now - HOW DARE YOU update that without my instruction?<br> Point 3 - The email address used NEVER existed on my account - HOW DARE YOU change my profile information based on a unauthed 3rd party???<br> I expect a written explanation, otherwise HL & I are leaving
