Ordered one thing and recieved another of half the price

Today i received my order, it was supposed to be a opinel no8 olive wood +*****th, now as a experienced woodworker this knife i received is nothing more than beach teak handle. The knife that cost half the price of the olive one i ordered. What now? Theres no more stock in south africa, and now I just have to be happy with the wrong product? What now? See the last attached photo, you sent me the wrong item, I paid for 750 and received one of 399. Thus this constitutes to theft under false pretenses!! Contact me asap!!
