ATM cash deposit not reflecting

I’ve been banking with FNB for years. After doing a cash deposit in Tyger Valley, of R 3,050.00 on Sunday afternoon (02/02/2020), the money was not reflecting in my bank account, nor did the ATM request my PIN number after inserting my bank card. I immediately called the FNB helpline and was referred to the ***** department. I also logged two disputes on their ATM as I was not just going to ignore this issue. None of these two consultants gave me a call reference number and I had to call back to receive them. Monday morning I was again in contact with FNB and the consultant kept me on the line, on hold for and hour and 5 minutes. I find this appalling service. I had to visit the branch in Tyger Valley to fill in a dispute form. The lady there promised it would be resolved within 2-3 days. I will have to wait and see. I will take matters further if this is not resolved. It’s theft and my trust in FNB has been forever tarnished. We’re supposed to trust banks but simply can’t. I want to close my account after all of this.
