After 25 years of democracy does nedbank use colour in order to determine level of service customers should received? I need answers ***

Pathetic, unprofessionalism, unwillingness and poor customer service in nedbank. For the first time after 10 years banking with nedbank experience an horror moments being abused by teller who claims to be professional but rudeness behaviour in stanger mall Nebank branch. After receiving numemous sms reads "Reminder. Your Nedbank debit card ..1265 will be expiring shortly. Visit your Nedbank branch with your ID & proof of residence today to have your card replaced." On saturday i was the first on the queue in the Nedbank kwadukuza mall branch to collect my Nedbank cheque acc card, i went inside assisted by front desk lady with ever smiling showing good customer service and gave me a ticket "002" I waited for 10 minutes before being attended by Teller name Pretorius, i gave him my identity and explain to him that i there ti collect my cheque acc bank card, he told me where is a message i received i told him that the phone was left in my card, he said the card was returned back due ti being uncollected. I explained that i need a card to use it how come i received an sms yet card is not in the branch, he failed ti explained this to me but showing a atttitude towards me and he was not seems willing to assist me either. Instead of checking where all received cards kept or escalated my matter to his supervisor he seems to be the boss himself in his own bank business, i was so hopeless valnerable yes i had to travel to free state where i Studied My Phd studies. I was in a cold, speechless on how the bank i used for so many years even opened my business accounts with nedbank having such person who dont care about clients affairs, service and assist where possible. I never had such dilemna in this bank i can name good people who serve us over decade in this bank with dignity, empathy and respect. Today at 07:07 20/08/2019 i received again same message reads "Reminder. Your Nedbank debit card ..1265 will be expiring shortly. Visit your Nedbank branch with your ID & proof of residence today to have your card replaced." Now something from nedbank must answer who is fooling who? Why should i waste my time and visited nedbank branch if did not received a message? Why should my colour of skin determine whether i should be assisted in a dignified, professionally, respected manner? I missed something here why it happened to me? Why must i received such treatment? Am i missed something here? Why after 25 years of democracy treated in this manner? Why should i continue banking with nedbank if it seems my colour will determine level of service i should received from the bank? I need written answers because i feel my rights are being violated here this matter need to be invistigated by human rights commision and banking association of south africa.
