Showing I'm in arrears when I am not

I have had the worst experiences with the Vehicle Finance Department Call Centre at Absa. I requested a statement and it showed that I am in arrears when I am not. Also does not balance with my current monthly statement. I was sent from pillar to post and nobody can tell me WHY. I am so fed up with them. They also charged me insurance while I sent them proof of my insurance SEVERAL times. Absa is so ***********. I changed my payment date to the 5th last year and it is still not reflecting. Why do I have to struggle so with them? Please do not finance your vehicle through Absa, the after sales service is appaling
