Complaint about the service

I called Standard Bank customer services on Monday the 2nd April 2018, I spoke to Puleng to assist me reversing three unauthorised debit orders that wet off my bank account. She took all the details and told me to hold on, I was on hold for more than 5 minutes without any communication until my airtime ran out, the call got cut-off. To my surprise only one debit order was reversed the other two not. The next day I called and spoke to Mandla and he took the details again and he told me it will take 24hours for the reversal to go through. The next day I was charged bank charges for unpaid items due to incompetence. Had these debit reversed on Monday as requested I wouldn't have charged so many bank charges. Service is bad, bad, bad. I hope they see my complaint and address it immediately because I've been with the bank for years and don't appreciate this kind of mistakes.
