Nedbank offers poor service

I have opened a new business bank account about 2weeks ago or more and I have not received any calls from my business banker. This is a problem because I cannot increase my spending limit on the card as he/she has to activate it.

I also tried to pay my employee using payshap and twice it told me that the payment did not go through. I then had to use the instant pay option, only to find that ALL 3 attempts went through. When I called the bank they told me that a reversal would cost me R400. I do not get why, because it was their app that was faulty. I am actually regretting opening a Nedbank business account. If I went with Absa, I would not be experiencing such issues.

I almost forgot, I actually tried to call my business banker Fatima, even whatsapped her, but I have not received any feedback.
