Old mutual and DCM

I had a loan with old mutual. I couldn't pay it any more as I was not working. The account has been handed over by old mutual to DCM. I called in this morning to make a payment arrangement. I told the lady I can afford R150 she said its impossible I need to pay R1000 and it didn't make sence to me because that is what I can afford and I need to at least make payment. I called in again after 5 minutes I explained the story to the consultant she said that is not true as you pay based on what you afford. She said that other consultant they are still trainers so she wouldnt know. I asked her for her supervisor to assist me as it seems like they are still new and not sure. She dropped the phone. This is so unprofessional and rude, I need this to be resolved today as I need to arrange a debit order. Old mutual please assist as I was sent to you to this company
