THE MFC STRUGGLES JUST TO FIX BANKING DETAILS

Since month one when we purchased this car on my wifes name we have had problems with MFC continuously failing to capture our correct banking details..the debit order does not go through and we get msgs saying it has bounced from MFC where we had more than enough funds in the account and can proof this with statements. My wife has called in more that 7 times to correct this error as they all said it shows its a cheque account whereby its a savings, they have confirmed it corrected but stil the debit order does not go through..we called agiain yesterday and again the agent noted that the capitec account they have shows its a cheque account STILL after many many calls we have made it is still not fixed.only April's debit order went off properly. Every othr month has been a huge struggle and again this month. Our bank does not even reflect a failed debit...what is going on WHY CANT MFC FIX THIS!!!! How much further do you want to mess up our credit score?? I will hand you over to MIOSA by tmrow of this is not fixed and we get an email with confirmation. JEANNE FITZGERALD
