Need to up their game

Firstly I would like to say I did get good service from Niti Bhatt the sales rep that assisted me in getting my loan processed. The funds were also paid within 24 hours as promised. However the afterservice went downhill. My debit order date is still inconclusive. I called the call centre when I received a text from Nedbank saying my first payment was due on the 29th September which alarmed me since I'd signed a debit order mandate. I spoke to numerous different departments who couldn't give me a diffinative date I payment would go off. Then I emailed Niti and she told me not to worry it would go off debit order on the 1 October. It did not go off. I emailed Niti again to which she informed not to worry it would go off 31 October but I must call customer service to be sure. There was no way I would call customer service again after my previous experiences.
