Junk service from the personal loan department

I am so ****ed with Nedbank's call center. I called to change my debit order date. Then I received a message to say the date was changed and that I have 4 months remaining on my loan. I only have 3 months left on my loan, so I called to query this. I spoke to 3 people and all of them gave me different stories. One told me my account is by COLLECTIONS because apparently I missed a payment! The other couldn't authenticate me because my WiFi is on??? Not one of the consultant were able to help me!!
