Bad service, unprofessional consultant Vela Mthimkhulu

I received and sms from FNB to go to any branch and update my daughter's account(she is a minor). I went to FNB Rosebank to do that, I got a ticket number with the waiting period of about 21 minutes, I eventually was called in to a consultant by the name Vela Mthimkhulu who assisted me with the updating, which took another 20 minutes or so. Once he was done, he then tells me that he has updated the details which will take place in 3 days and if that does not happen, I will have to come in again and opened a new account for my daughter. I got a little disturbed as I felt that he should have provided me with all the options before he could start with anything. I told him that unfortunately I do not have time to keep coming to the bank and asked him why he did not tell me all this options because I would have opted to open a new account as I was already at the bank and had all the required documents. He then gave me an attitude that I will have to come and open the account either way without being considerate, he also did not want to acknowledge that as a service provider who knows the systems and information about FNB, he ought to have told me before. He then started laughing mockingly on me and when I told him I will take it out with the manager he said "I do not care" I then asked for someone who is superior, her name was Sarika who I feel did not handle the dispute well, she also did not understand my point. One good thing about her is that she used the word apology though as we were discussing, she was siding with her staff member. My question to FNB is, really is that a way we treat your clients, what does providing service and offering advise mean. I also wanted to open a personal account for myself which I ended up not opening because of the bad experience, you have lost a client over Vela Mthimkhulu who undermines people, does not have respect for clients and full of himself. I wonder if I was gonna be treated like that if my skin colour was different.
