Not giving the right information

I took out a loan from Bruma finance, about a month ago they phoned me with a proposal,stating that I can get a new loan. The consultant over the phone clearly stated and told me that the old loan will be settled in full and will be closed. He said that I will be starting a whole new loan from start. I received an SMS telling me that my account is in arrears,when I spike to them earlier in the week they said the old loan is still active,and that I am paying 2loans now. When I took the new loan I clearly asked the consultant if the old loan is going to be closed completely and he said yes. Now all of a sudden I must pay for a mistake that is not even mine,but I must now pay for someone else mistake. This is unnaceptable. If they told me that over the phone I would have never taken out the new loan.
