Using my email for one of your customers is *****

They are using my email for one of their customers Sizwe Mhlanga. I have sent numerous emails because they are sending all of his documents to me. I wonder if they are aware that is *****. Their agent Faith Kente responded arrogantly that she has removed my email and then 2 days later I get the email again with documents to view. I wonder who is this Sizwe Mhlanga person and why my email because all my accounts with oldmutual were closed more than 10years ago and why my email. Please remove my email from this man's account.
