Dissatisfied

I have an account with Nedbank, and then I took a personal loan sometime in February, and then my contract at work ended. I then contacted Nedbank to make an arrangement to pay the loan. The arrangement did not kick in April or May June, I continued making full repayments even though I was not working. July I called in again, and they said the arrangement would be set I received an sms confirming that. Last week I got a call from a lady confirming that an amount would be deducted and i said if possible then could debit that, and she said let us not disrupt what has been set on the system. I agreed then end of the month no money was deducted. I called them and a lady by the name of Zanele said there was no arrangement made, i then said i wanted somebody to listen to the recordings so that we could get to the bottom of this. She then said she would let the supervisor call me. Instead, I got another message confirming the arrangement. On the 4th of September, a full amount was debited from my account and I called them because I cannot have a debit order since I do not have a salary, I spoke to Lebo and she listened to my story then the call got cut. Nobody from Nedbank has gotten back to me regarding this matter
