unfair treatment

My car was repossesed in October after I failed to pay in August.When I asked the bank how much I need to pay to be up to date I was told 450 000 because the bank and high court cancelled my contract and I need to pay the money immediately no negotiation even though I had already paid 22 000.I asked my lawyer to followup the matter with the high court but my file was empty.<br> What amazes me is the stamp on the summons was April and the car was only taken in October whilst my account was debited except June they did not debit it even though funds were available when I check my records.I acknowledge that August I had financial hiccups and had already fixed the problem.I am not getting any clear explanation from the bank what made them to take such harsh decision against me.I don't even have a document that explains the process,and the issue of April stamp and Sheriff stamp in October and them continuing to debit my account,I can't match anything and I am confused now that there are no records even at the High Court. I need an understanding and clarity even if I can be on the wrong which they also need to clarify to me.No communication of what is happening about this issue.
