********** attempted transaction, indicating an inside job.

Yesterday I received a call from somebody named Zandeile *** who claimed to be from FNB ***** Dept. It was regarding her querying a transaction attempt on my husband's Credit card. Strange why he wan't phoned directly? The attempted deduction amounted to R15066.00 at Nedbank Masterpass & using the last 4 numbers of my husband's card! This lady knew a lot about the card details but asked me many additional questions. Fortunately, I wasn't prepared to supply the answers due to feeling suspicious about her. Therefore, requesting that she emailed details of the attempted transaction. She informed me that she would have the card cancelled but gave no reference no. Also, she did not have our correct email address so I gave her an old unused one! No email was received into that old address, so I telephoned FNB ***** people to check if her call was genuine. No it wasn't, so immediately instructed that the card be immediately cancelled & received a reference no. Since he recently received the Credit Card, it hasn't been used. We strongly suspect that the failed attempted ********** transaction was an inside FNB person. Nobody else would have had all the information. FNB is requested to investigate & take action as I supp**** the caller's cell phone number.
