Please give me back my funds!

I have been waiting for a refund on my account for an unauthorised debit for close to a month now, Capitec promised that I would receive it within 7-14 working days from sending the necessary information. For a bank that prides itself on simplified banking, this is not it and it’s so fair. They have just kept quiet, I did a follow up and I just received a mere email stating that the card department would come back to me and that was a week ago.
