Consumer rights violated

Good morning

I’m writing this email regarding customer service I’ve been experiencing from Nedbank. Let me start here, I opened a credit card with them, and the lady from applications was not even updating me nor reply on my emails and o ended up assisted by a team leader ( Angel Nkosi ). She assisted me till the i received a call from the lady from applications and she told me that my application has been approved and I’ll get a notification sms for the card collection, still there i called angel to check if it true and she said yes I’m the one who send them an email to speed up your application because it was long overdue. And she called me the next day regarding the collection of my cards. I went to Kwamashu nedbank for the collection and only to find that I did not carry my id with me I only had a temporary id and passport. I got to the bank and went to the teller and he said to me I can not assist you since you don’t have an id and I’m not fica verified. I told him I have temp id and passport and I also have my I’d on my emails and he gave me his email to email him my id and I did. After few minutes he said it not gonna happen since I’m not fica verified. I came out of the bank went to check the flights and I called the Nedbank call center to ask if they can assist me regarding this matter and they said to me mr mtetwa don’t stress because you are fica verified go back there they will assist you. Went back there looking for the guy and they told me he just left now now and I went to the manager and told her that one of your stuff members gave me false statement. And I called again in front of the manager to confirm my the statement that was given by the call center agent and she heard her self that I was fica verified and she sent me to counter no 4 for assistant. Went there and did the finger prints and everything was in good order until we reached the activation of the cards part. The teller found that the card were on a bad hold and I asked the lady what does that mean and she said she will call and find out. She called and they told her that my card are under investigation for ***** application and I was shocked. Then I leaf the branch went back home. While driving down the estate I called to find out what happened and they putted me through to the candidates that held my card and I ask the guy what went wrong and why is this happening now and he rep**** rudely and said to me you can not tell me about how I must do my job and I told him that is not the way of communicating with a client and he kept on shouting and I told him that you not the owner of nedbank and the calls are recorded and I will deal with you formally then I dropped the call and I sent all email to the angel and she rep**** via Email as well siya Mr kelvin Chaka said to her this is a ***** matter and we shall be notified once they are done. And in the morning I called the call center wanted to speak to Mr Kelvin Chala’s manager and I ask him what is wrong with my application because everything was done by the relevant department and they found nothing and he ask me about what do I do for a living and I thought to my self my be that is part of ***** and I told him that I out Sorce event equipment and engineering consulting ect and they stated to ask about 100 000 that was sent by my client and they wanted to know what was it for I told them that is was for a service and the manager ask me to send him my client’s contacts number and I told him to wait 5 to ten minutes. I drove from Zimbali coastal estates to umhlanga to get the number and I called the guy to give him the number and he started to ask me about my I’d and I told him it in Sandton and he said I must call the once I get to sandton so that I can do things this side and I said ok even though o felt violated. Lastly I call in again and looking for a manager of the call center and I stated my story and she said this in not a good customer service and she advised me to report it to nedbank complains I did and she called the mr kelvin’s manager to follow up and told the lay that they will call me in few but they never did. I really don’t know what to do please help me

May thanks Ayanda Mtetwa
