Personal Loan: Still waiting after 4 weeks for an outcome. Shoddy customer service!

I app**** for a personal loan telephonically with a lady by the name of Carol on the 30/11/2021, I got an offer and signed my pre agreement forms, which I had to send back to them. Since the first phone call I have never received any updates from Carol or Nedbank with regards to my application, the only way for me to know what was happening was if I called in myself. Whenever I tried to get Carol on on the line she would be busy on a “other” call. Bare in mind I’ve called more than 10 times and she was unavailable all 10 times. I would then get a one sentence email back in response, very unprofessional. A banking institution of Nedbank’s stature should be way more efficient, every time I call, I get told there’s problems with my documents, I’ve sent all my documents more than 3 times already. And as I’m typing this l, I’m still nowhere near knowing what’s happening with my loan. I’ve been with Nedbank all of my life, never expected such shoddy workmanship and customer service.
