Double deduction without authorization

Nedbank, On 28 September 2019, you double debited my account. On 17 September 2019, I received an SMS to advise my installment will be deducted. I always pay my installment every month plus an extra R566. I was not aware that I need to make an arrangement every 3 months to make a new arrangement,until Nadine advised me I need to do so. So I made the new arrangement starting on end October to deduct the R566 and sent a refund request for the extra installment amount to be deducted. I'm so grateful for her calmness and understanding. When I checked my account now, another amount of R662.19 was deducted. My child's school need to be paid and other debit orders still need to go off.

I did not authorize Nedbank to deduct these monies and need it to be refunded and the arrangement will take place from end October as agreed with Nadine today!!
