Cash Deposits Simply Disappear

During the month of May 2019, my wife made a total of 4 cash deposits totaling almost R3500.00 by making use of the card-less cash deposit facility at various local ATM teller machines. With each of these deposits, not one single transaction receipt was printed/supp**** by the Auto-teller as in true ABSA style their teller machines seem to be permanently out of paper. At the same time, their SMS notification system also did not work, so one could only hope and pray that these transactions were successful. Now just imagine my utter disgust and surprise when I received my May 2019 Account Statement only to discover that not a single one of these deposits reflected on my statement. Since then, my wife has been struggling now for two months to try and get an answer from someone (ANYONE!) at our local ABSA branch as to where these deposits have disappeared to. To date, no answers have been forthcoming! What I cannot understand is this: When making a card-less cash deposit, one needs to enter a). A reference Number, b) An account Number and C) Your SA ID Number. So with all of this info being provided at the time of doing the transaction, how difficult can it REALLY be for ABSA to track and trace these failed transactions? Hoping to get an answer SOON!
