No response to refunds request...order at your own risk !!!

I made an order on the 04 May 2025 at night then on the 5th May at about 13h00 I then cancelled all orders on their system and when I didn't receive any cancellation confirmation through SMS nor email, I then send numerous emails everyday from the 5th to 8th then to my suprise courier arrive to deliver orders that I have cancelled before they were even processed nor handed over to courier. I send the courier back with that order without even taking it from their truck. Then Makro have an nerve to refund R15 instead of R646.00 for ORDER OD***. When you order online, you receive a "thank you for shopping with us" when you cancel then you receive to emails nor SMS and also NO ONE RESPOND TO THEIR EMAILS...THEIR SUPPORT STAFF MUST BE SLEEPING 24 HOURS.
