Bad service

I am not happy with their service November I spoke to their employee and she assured me that she will stop debit orders from debiting to avoid charges since there's no money coming in my account and that is will reverse debit orders for November now my account is on minus with R6800, who is going to pay for that because I was told they will stop my debit orders and when I have an income I will contact the service provider to carry on with the debit orders.
