Nedbank Lenasia horrible service to long standing client

I am deeply dismayed by the service provided to me at the Nedbank Lenasia branch. I have been a loyal client for over 25 years, having had two home loans and three vehicle finance loans, all of which are now fully paid off without any missed payments. Recently, I app**** for a basic credit card primarily for online business purchases. Despite applying in January 2024, I received no feedback until I personally visited the branch three times, with the last visit being yesterday. My application was denied due to allegedly incorrect information uploaded, despite me providing accurate details during my initial visit. Despite promises of feedback by today, I have yet to hear anything. Tomorrow marks my fourth visit for the same issue, which should have been resolved online. As a property owner with two properties, five vehicles, and a successful business, boasting an excellent credit score, it is frustrating to encounter such hurdles for a basic credit card. Moreover, the attitude displayed by the staff, including the manager, has been nothing short of arrogant. When I mentioned that both FNB and Standard Bank had pre-approved me and that I might consider switching, the manager's response was dismissive, saying, "Well, we can't stop you if that's what you want." Such behavior is unacceptable, especially considering my long-standing relationship with Nedbank.
