Incompetence and lack of accountability

I ordered a sandal a week ago, instead I received a pair of man sneakers with a packing slip that has my details on and my shoe order. I contacted the online customer services and they generated a waybill and promised me that a courier will pick up the shoe and they will assist me get my order since their coastal stored mixed up mines with someone else's. To date I'm still waiting for their courier to pick up the wrong delivery, in fact I just want my money back there is just no accountability or professionalism in this store. My order no. is 324494, I just want my refund and never will I ever purchase anything from this store in my life.
