FNB cancelled my card without my knowledge and charged me for a replacement

FNB cancelled my card without my knowledge and then charged me for replacing it. On the 08th of August at 07h54 I received an FNB notification SMS informing me that my card was cancelled. I called in and was informed that my card was cancelled in error. On the 13th of August I went to the Montclair branch and the consultant told me that my card was cancelled in error and she attempted to contact the person who cancelled my card but his/her extension was not answered. When I checked my fees and transactions I found that FNB had charged me for replacing the card when they cancelled it in the first place.
