Vericred Debit orders

I call Vericred last month and asked them to reduce my debit order . The lady I spoke to promised me a call back the next day so we can finalise it on the system. A never got a call back. I then called them myself and they said it is now too late and the deduction is already running so I will have to reduce the next debit order. I asked her if I should give them a call back and she said no, the system will automatically do it. The debit order was never reduced and my life is a mess right now because of that. I called them again last week and the phone was answered by Edward who confirmed that the person I last spoke to is Sinethemba and he transferred me to the debit orders section, and I spoke to Nozuko who then promised me a call back “Again” the day and she never called. I never asked for this debt, I am not even employed yet. Something must be done about this
