Worst experience and poor customer service

My car was settled on the 20th December 2023 and they still went and debited my card. I called them on the 29th December 2023 for my refund and they ask me to call on the 30th December 2023 which I did. I was informed the money still not reflecting to call again or when they see on their side it will be refunded back.I called on the 02nd January 2024 and was put hold numerous times and was told they might be possible of refund and I kust not reverse the amount. I am sitting at home without funds and Wesbank consultant is telling me to wait for 5-7day working days where as that was for my child school fees. Why must I wait 7 days for the money that did not belong to you guys and the incompetence of you now must cost my son fees which he will not be enrolled in school because of your negligence
