Terrible service

Good Day. I placed an order on the 26th November. It was for 2 t-shirts and an asics gt 1000 shoe. I received the two t-shirts the following Friday. One was stained and needed to be returned. I called the customer care on Friday amd spoke to Mateo. He said the shoe is still with the courier company. I should receive during the weekend. He would check with courier and email me. No email received to date. I called again on Monday the 7 Dec. I was told it is still in the store in Cape Town and cant say when I will receive. Orders are supposed to be received within 5-7 working days. Today is the 7th working day and I have no idea as to when I will receive. I am suffering from knee issues which is the reason I purchased this.
