Poor service and very rude

I have done an application telephonic for the credit card. After the application was told to email some document to complete my application. Then after was told to go the branch to submit the the original documents and update my number which I did. Today I made a phone call to make a follow with my application the lady who was assisting me Lebohang Mabuse said I need to go to the to update my cell number since they have an old number that I last used in 2014. I asked her how possible is that they have the old number but they have been communicating with on the new number. She said she doesn't know and she can't assist me further. And I told her I have been to the bank already to update the number and submit the original. And the lady who was assisting me had said the card will be delivered at the branch at Northgate.

I then request to speak to her team leader. She told me that her team leader Nishi Ganpath said she's not interested to talk to me. I must just go to the nearest branch and there's nothing she can do for me. What shocked was that she was not even willing to talk me as their client. Because I would have asked her to get the card delivered to the branch and i will update the contact again at the branch when I collect the card.
