Absa AVAF double deduction in December

I received an sms on the 14th of December that my vehicle finance will be deducted on the same day. They deducted the amount twice both on the 14th and the 26th . I have been calling the vehicle finance contact number for the past 2 hours with no success. I need that money so my other debit orders can go through today. This is very unprofessional of absa to assume that firstly everyone gets paid early in December and secondly deducting the amount twice.
