Nedbank doesn't care who your information goes to

Good day<br> <br> I bought a new MTN cellphone and sim card and it so happened that MTN gave me a recycled number (someone else's previous number). The problem occured when i started receiving the other persons notifications on his bank acitvity. I can literally see whatever someone else spends his money on and where he buys it from. I called Nedbank (because they are doing the information breach). I was told they can't remove the number from the account because it is not my account which makes sense.<br> <br> I asked them just to find the person who the account belongs to and ask him if the number can be removed from his profile. I work at Absa and this should be a massive issue for Nedbank because it makes it easier for me to commit ***** by having this information. MTN is equally reponsible but they arent sending me sensitive information.<br> <br> Just imagine all your account activity is sent to someone you don't know.
