Absa vehicle finance is a ****

Absa vehicle finance is a ****😭now is the third day they haven't debited the installment from my bank and money is there. The reason am furious is because in 2017 I had to deposit the installment 3 months consecutively so because of them delaying to debit money, when I had to apply for another car in 2018 I was regarded as a bad payer because of them not debiting money which was available in the bank. I hope this time history won't repeat itself I can't afford to ruin my credit score with Absa poor service. I hope my account won't be in arrears due to their fault
