MFC Nedbank

N bought a Ford Ranger through MFC Nedbank . I was under dept review die to financial problems.... I got in arrears with my account....yesterday they came and fetch my vehicle die to the account being in arrears. They said when I pay the account up to date I can get my vehicle back.. I was given emails and numbers to contact for the arrangements. I have been phoning my battery dead and also emailed them but can't get a hold of someone....I have the money to settle the amount in arrears but can't get a hold of no one..... This is a poor service from a big company..... I just want assistance to get my vehicle back.
