FNB Giving Personal Information To O'keefe and Swartz

So I get another call today from O'keefe and Swartz with regards to my Classic Credit Card at FNB, They have all my information and my current accounts at FNB this can only be possible if the information is given to them from FNB. These people are phoning me non stop and say they have the full support of FNB. They are trying very hard to sound like FNB and are even using the same script verbatim that a usual FNB call starts off with. I want this to stop how dare you give peoples information away to call centers that are clearly trying very hard to trick you into thinking you are talking with a proper FNB consultant. Get your acts together and get hold of this company and tell them to stop their **** enough is enough.
