Client Statement and internal system not corrospon

A Debt Collector phoned me to repo my vehicle but my statement stated that I'm up to date. The outstanding amount in the 0-30days Colum. According to the debt Collector I'm behind 2 months. The statement sent to me on 15Dec states that I'm up to date as the same statement the Debt Collector send me. How ever on the MFC Transaction list it shows I'm outstanding +- R7000.00. No one from MFC contacted me after my statement was sent on the 15 DEC 2015. No other notification was sent to me regarding my account. and on 12 JAN 2016. The Debt Collector phoned me to collect my vehicle. This is totally unacceptable since in the first place my Statement shows I'm up to date. And NO ONE from MFC contacted me after my statement date their was no other communication sent to me. How can they say I'm behind if my Statement clearly states that I'm up to date. And then further sent the debt Collector to arras me for nothing.
