Impossible to switch a debit order! ZERO response after almost 4 WEEKS!!

I have been awaiting almost 4 weeks just to have my debit order updated!! After numerous e-mails, I have phoned twice, as DirectAxis insisted that I call to have this done. The last time I called was last week Thursday 17/6 and spoke to Lance Baily who was a trainee - he was very friendly but explained that he is still learning and only appointed to capture the requests, he promised that someone from his team will give me a call within 2 working days. Today is the 23/6 and ZERO response received from them!! I am taking this to the ombudsman, if it is not sorted within the next 48 hours. My debit order is due on the 25th and will not be going through as my salary is now being paid to my new bank account (Nedbank). ALL the details have been provided within sufficent timeframe, but DirectAxis is delaying! The worst service ever!! Very quick and efficient to give you a loan, but there after sales service is close to Zero! Account No: ***
