Reservation refund not paid

I was interested in buying a vehicle in the Midstream branch. I paid R2500 reservation fee. After receiving second opinion I decided not to continue with the purchase. I communicated this with the sales assistant, Khutso, on Monday 20 Jan 2025. He asked me to send him documentation in order to process a refund, which would take 72 hours. I have not received a refund up to date. I have asked him to share his manager’s contact or his finance department contact, he said they’re not allowed to share such information. He advised he would ask them to contact me, no one has been in contact with me and no refund in over a week.
