ZERO CUSTOMER SERVICE - CARD DISPUTE DEPARTMENT !!

I submitted a Debit Card dispute form on their request on 13th of February (Ref. # ***) after a unauthorized card transaction/deduction went off my account on 9 February. I tried following up every day, without any success, getting transferred from one dept. to the next division or getting a stupid robot responses saying the dept. Is not available. I tried numerous complaints via customer service (Ref. # *** / # *** / # ***) stipulating it was assigned and they will be in contact shortly. I went into my branch and a lady by the name Angel Sibisi tried to assist me .. nothing, she got just as agitated just to find out there is no contact number for the "Debit Card Dispute" division for business banking. She send a mail on 8 March requesting urgent feedback .. guess what ? Still not even a phone call from this dept. with any kind of feedback. Absolutely useless to say the least !!!! Had to cancel my cheque card to avoid any other deductions as well.
