VERY Poor customer service

I contacted Nedbank on the 27/09/2019 to apply for a limit increase on my greenbucks credit card and was told I will get a response in 5 days, I only received feedback via sms on the 08/10/2019 and was told that my request was provisionally approved and that I should send 3 months bank statement or 3 payslips, I sent the payslips within minutes, I followed up on the 11th and was then asked for bank statements, which I sent immediately. I followed up yesterday calling the call centre and was put on hold for long and was told someone will call me back and its midday and no one has returned my call. I have again sent an email to the consultant that I sent the doc to Thembalam and there is again no reply to my emails. All I want to know is the verdict of my application.
