Worst level of service and urgency to a card dispute transaction that got paid twice from my debit and credit card

I've been a client of capitec bank since 2006. I've logged a call on 16 Sep 2021 because a Takealot.com transaction was paid from my debit and credit card. I've tried getting the issue resolved and phoned both parties. Capitec bank logged a card dispute and gave me the reference number and said that they will have a 2 to 3 week turnaround time with the one transaction being reversed. UP TO TODAY, they didn't phone me of contacted me back regarding the matter. I've phoned them 4 times since then and the same old story "it's at the dispute department and will be appointed to an agent once there is an agent available" I am so fed up of this poor service and level of urgency they give to a mistake that happened between them and a third party. I am on my way to close my accounts with them as soos as "the next available branch don't have a waiting que ending in the streets"
