ABSA VEHICLE FINANCE *Incorrect Debit Amount

AVAF, pathetic service, I recently opened a statement for my vehicle finance and questioned two amounts, I contacted ABSA they directed me to a third party, I contact the third party they mentioned its ABSA's issue which makes sense as they are the ones debiting my account. I contacted the. Credit life & Mantaince Warranty department with little success they can't seem to explain the R406 on my statement? How is it possible that nobody at ABSA can assist me? Count on them to debit my account on time this month though!
