How DARE you??

This morning I received a phone call from a woman calling from Stoepel & Berman Attorneys on BEHALF of Standard Bank. She says that Standard Bank have enlisted their services to update peoples personal information i.e. telephone numbers, if my salary is still being paid into my cheque account....etc JUST WHO gave them permission to pass my personal details over to a 3rd party? Just WHAT information has been given to them?? My login details?? I NEVER gave permission to Standard Bank to do any of this.... this is a breach of my account's security and my right to confidentiality!! Just WHO do you think you ARE?? DISGUSTING!<br> So by the way, some strange person calls and asks me for my personal details.... do you really think I am going to give ANY information to ANYONE telephonically?? I am not that stupid!
