No client Service, we are not a priority to them, so unprofessional! Im done with this bank!

I sent a request to fnb to reverse 2 payments, two days after I inform them to cancel both requests as I will be refunded, only to see weeks after, FNB decides to deduct an amount for the “service” conducted to reverse payment, but they didn’t even do anything as the request was cancelled, and how can you deduct a service fee for one reversal and not the other? What are you people trying to pull , I’ve made contact with FNB to try to request they refund me as this was the last money I have left in my account to buy food for me and my 2 year old daughter and still I’ve been in contact with them almost THREE weeks and still no refund received, after they have they nerve to ask me to send them proof that I’ve sent a request? Are you kidding me? If you received cancellation for the one then you definitely received cancellation for both! I’ve been with FNB for more than 20 years but now I’m so done after this! Pay me back and I will cancel you as me fsp this is so disappointing but so ridiculous!
