Pathetic service

I app**** for a credit card on 17/4/2019, after a week and a half of no correspondence I called in for feedback and was advised by the consultant that the application is still pending and I was requested to forward a copy of my ID - which i did. The agent assured me I would receive feedback within a few days as my application was still within SLA. Another week passed with no contact so I called in again and spoke to a different consultant who told me the application was approved for R43 000 (I did not ask for this credit limit) but there is a problem and the account needs to 'taken up' and added to my profile and the cards need to be ordered. The agent advised he will have this sorted and I will receive feedback once my cards are at the branch. Another week passed with no contact so I called in again, this time I was advised there is no record of my application and I must call back the following day to speak to the sales dept because for whatever reason they were not available at the time. I called in the next day to speak to the sales dept but I was again requested to call the sales dept later (this time they couldn't take calls for some reason). Eventually I got hold of the sales dept and was advised there is no record of my application and I must apply again, to which I refused and requested to speak to a team leader. I was advised by the team leader that he will investigate the issue and call me back the next morning with feedback - no prizes for guessing that he did not call me back at all the next day. I called in once again, spoke to the team leader and advised that my application was approved but then declined at verification due to my 'reaching my allowance' and then proceeded to offer me the chance to apply again - which makes no sense. Why was I not notified at any stage of the application? Why was my application declined for 'reaching my allowance' when I did not request any specific limit? Why was I promised and advised my application was approved and I would receive my cards? I have not received any plausible answers to any of these questions. I have had issues with Nedbank before but this will be the first time I am making a complaint. This experience has left a very sour taste and after years of being a client and previously an employee of Nedbank it is now time to end my association with them as soon as I can.
