Terrible Experience

I placed an order online for a couple of things on Friday morning, 5 items on the order were cancelled because even though the items were marked as "in stock" they were actually not available. I called in on the same to cancel the whole order so I could just go to the shops in person and get what I needed. I was advised that the cancellation will take 24-48 hours and the refund 3-5 business days. I've contacted the Game call centre and Whatsapp chat each of the past 5 days to enquire when the cancellation confirmation will come through and everytime I get a different response. Monday I was told Finance is processing the refund, today I was told they are still working on the cancellation. Absolutely appalling service. I would not recommend using the online platform
