Wrong order!!!!

I placed an order online on the 16th of April. Today the 23rd of April I receive a completely wrong order but the box has my details on it. None of the contents inside is what i ordered. I needed the clothes for a vacation i have next week and i am told i will get a reply after 48 hours!!!!!! Mind you working hours! Next week is full of public holidays clearly i won’t receive my clothes in time for my vacation even though i ordered in time. This is pathetic!! Horrible experience with Mr Price online, you guys better sort out the mess up you do with our orders in those warehouse. This is unacceptable
