Settlement of Arrears

I clearly recall being contacted by Vodacom when my account fell into arrears on around June 2017 and my arrears was R2962.66 (consequently my contract ended in May 2017), I made arrangements to pay R300pm and made payments on 08 June 2017 and 18 July 2017. Whereafter my balance should have been R2362.66 . My account was handed over to MBD attorneys for collection. They advised me that an amount of R4500 approx. was handed over to them by Vodacom on November 2017. Interest for that few months could never have doubled what I owe. MBD now advises me that I owe R5100 approx. and settlement discount is R200 (wow!) . Anyway I asked MBD to provide a statement of account so that I could understand what was being claimed and if satisfied I would settle amount owed. MBD clearly explained that they cannot provide me with a statement. So I am stuck between a rock and a hard place. How can I trust that the amount claimed is true and fair? I can't ,which means I can't pay MBD attorneys. I am told by Vodacom Legal that I can't deal with them directly as I have to go to MBD ,unless MBD sends my account back to them. Times and tough and a vast majority of households are drowning in debt. I finally have the means to settle this account but it seems I can't . I simply want to settle this and move on and Vodacom is making this exceptionally difficult. I would like to deal with someone from Vodacom who has the authority to recall this account from MBD attorneys and provide me with the statement of account so that I can settle. I do not want to deal with MBD and their incompetence. Account number I ********** 0
