Debt consolidation

I have started paying Admincor Associates and amount of R600-00 from the 31st of January 2009 until the 31st of March 2011 which comes to a total of 33 months of payments and the total amount of R19 800-00. I changed jobs and went to Statucor (Pty) Ltd and from the in September 2011, I resume with my payments of R720-00 which came to a total of 53 months of payments including January 2016 and the total amount of R38 160-00 which brings the total payments of R57 960-00 that I have paid to Admincor Assocaites. The amount that I was supposed to pay it over to you is R35 030-00, whereas I have already overpaid your company by R24 130-00. When I requested the statement they would give me wrong figure that does not add up.
