Refund not processed

Pick n pay has a support email that they never respond too on top of giving clients misinformation about how to return their items and get their refunds. I called their support centre on the 26th of November 2022 about returning items that had gone off special because my order sent on the 25th was only delivered on the 26th. On arrival at the shop I was told that they should have processed the reversal before sending me there but the staff offered to call and assist. 7 days later there's no communication nor reversal of the funds, evident on both the card and wallet. I have logged a call to their system and it was acknowledged yet no one has called to check the issue. Highly disappointing
