Absa is completely ***********!

Absa is completely ***********. Sold and settled my car on 13-Apr-2018 yet they still deduct the installment on 30-Apr-2018. Phoning their vehicle finance number ***I had to hold on for more than 10 minutes to be assisted. They admitted their mistake and lodged a refund. I however have to wait up to 3 working days to get my money back, yes same bank, but still 3 days. I am now out of pocket with a large amount of money and cannot pay my other debts. Meanwhile they are sending me sms's to say my credit card is overdue and I must pay. Absa, are you completely stupid as well? If my money is not back in my account by close of business today Wed 02-May-2018, I will trash Absa on social media for the *********** bunch that they are!
