Bad Customer Service

Hi recently opened a Nedbank savvy account. The card was at the Scotsville branch and noone told me the card was there. I eventually got the card. After the consultants at the branch assisted me to update my contact number I found the the contact number is still the old number. Around the 15/04/2020 I requested to have an American Express card linked to my account, I was contacted by a consultant by the name of Kyle Meth via telephone who advised me that the cards will be at the Taj branch within 3 to 5 working day and that my existing mastercard will be cancelled once the new cards are issued . The days went and I got no response from Nedbank. I then went onto the online chat and spoke to a guy named Timothy Link on the 23/04/2020 who then told me the cards will got the Liberty Mall branch as the Taj branch was closed due to COVID-19. Timothy advised me about a platinum account and that if I converted my savvy account the cards would get delivered to me free which I said no to and that he will provide feedback. Today I sent Timothy 2 emails about feedback and got no response. I even agreed to pay half of the delivery fee of R150. This is really appalling service from Nedbank. I am very upset with the lack of communication Nedbank has also at the lack of customer service they have for their clients. Please could someone senior assist me to get this sorted out asap.
