Unfair treatment

I placed an order online on the 6 of December- order number SC73265 I received order confirmation on the 10th of December, that its on the way and indeed i received it on the 11 of December 15:42, but guess what it was missing 1tem. I then sent them (Shoe City) an email, first thing in the morning 12Dec @07:45, with a screenshot showing them the only items i received. I got an auto-response, which is fine indicating they are experiencing some technical difficulties, and a case has been logged for me with the customer care team. To this date 15/12/2025 @14:12 , i haven't received any correspondence from them, can you believe it ? talk about treating customers unfairly. I would like some prompt feedback regarding my order before i escalate this issue to the NCC for unfair treatment & lack of respect.

Thanks,
