Absa vehicle finance

I settled my vehicle that was finance by absa a week ago. I didn't receive any communication, so I emailed them and was told I have to phone absa vehicle finance call centre. Both of the number that was provided asks for my ID number, which I then get told was invalid. There are no options to speak to a consultant. To make matters worse, absa has now deducted another payment for the vehicle that I settled a week ago. I phoned their main contact center and I am just get put through from one person to the next. I feel that their service is disgusting. I have no idea how I am going to get my payment back or my ownership papers for my car and I am leaving the country in 20 days.
