Horrible service ever received

I have never received such horrible customer service from Nedbank like recently. On the 17th of December 2020 i logged in live chat via my nedbank app to order new cards as my cards are expiring now, the end of January. The agent that was assisting me ended the chat before I could tell her that I want my cards to be delivered at Sam Ntuli Mall and not my branch since I am working at home. I then received a notification on the 29th that my cards are at Flora Centre, which is what I didn't want. I then called the client services and requested that they send my cards to another branch and was promised by the agent that he had requested cards to be delivered at another branch and that will take 3 to 5 days, NOTHING UNTIL NOW. On the 19th I then decided to follow up and the agent that assisted me explained that the request wasn't done and explained that I would be charged more as they had already sent the cards to my branch. I was not happy with that and asked her to escalate to a team leader for this to be sorted. I spoke to a team leader from Durban called Avi and she advised that she would need to investigate and would come back to me after an hour, she didn't UNTIL TODAY. Yesterday I called again to follow up from the team leader, she didnt want to speak to me and asked the agent that was assisting to get my details(which I gave to her on Tuesday) and she will call me back(NO CALL BACK AGAIN)the agent also said she will call me before the end of business and find out if the team leader called me (ALSO NO CALL BACK). So in essence my query is not resolved and still don't have my cards from my trusted bank . I am now sitting here thinking that its best to change to a bank that cares about their paying clients and don't have to beg for the service I pay for.
