Outstanding refund from Makro

I purchased two items from Makro online in May 2020 to be collected from Makro Centuriion. Days after my EFT payment, I received a message from Makro that one of the items is cancelled because they are out of stock but my debit card will be automatically refunded. I then collected the second item at Centurion. I was also told that I should not worry about the refund because I will be paid automatically within 7 working days.

In august I noticed that i am not refunded. On the 14th August I drove to Makro Centurion and requested my refund. They called their call center. Mr Moeketsi Mokoena from the call center informed me that I should submit a refund request by email and attach supporting documents. He assured me that I will be refunded within 7 working days. I submiited a claim request as per the instructions on the same day. Up until today I have not received my refund of R1 400. I have made several calls and revisited makro centurion with no success. Makro always confimrs that my refund is due but their head office finance department has not processed it or indicated when they will processed it.
