Received wrong online order and highly disgusted with level of service

I placed an order online, Kindly note the order number: ***. I have wasted so much time on the phone, WhatsApp, and email. And still have not received a resolution. I emailed a complaint to Mr Price weeks ago and have still not received a phone call or a reply via email. At this point, I am emotionally upset with the situation. I placed an order for a desk fan as it is extremely hot in my apartment and received a mini pocket fan. I work from home so I accepted this mini pocket fan and purchased another fan from another supplier since Mr Price could deliver what I ordered. All I want is the price to be adjusted because the item I received the value is a much lower value than what I ordered, and I have been billed for delivery. I find this unfair as it was not my fault Mr Price sent my account. The price difference is not that major, but its the principle. Should Mr Price resolved my query weeks ago I wouldn't be writing a complaint. I would like the amendments on my account and waive the delivery fee for the inconvenience
