Sanlam Personal Loan

I was contacted by the Nimble Group regarding an outstanding amount of R275.30 outstanding balance on my Sanlam Personal loan account. I informed the company that this was not the case that ny Sanlam Personal Loan has been settled for an a very long while now, and that Sanlam actually credited me money for overpayment. I was told that I needed to phone Sanlam and speak to them and get proof of settlement. I contacted Sanlam and spoke to the call centre agent was told that the account was indeed paid and that since settlement that the debt review company kept on paying the account and that there was again an amount refundable to me. I was then promptly informed that they wont be able to refund me the money because the account was closed by another department and proceeded to put me through to the department, I was put through to the Nimble group again (attorneys) I spoke to a Mr J Nel (Ops Manager) and was told to contact Sanlam as they cant help me. I spoke to the call agent again and was again put through to the attorneys. After numerous attempts to get some at Sanlam to help i referred the matter to the Sanlam Internal Arbitrator for assistance. I am simply cannot get any help!!!
