falsely advertised vehicle

Bought a BMW X4 from SMD pretoria east. vehicle was advertised with all angles of the vehicle showing including underneath, etc. none of which showed the engine laying on the floor. according to pics including engine and underneath, it showed everything to be intact. if it was shown as the engine on the floor i would've big accordingly. the advertised product and the actual item collected were honestly to different things. please assist in this matter as it genuinely is a falsely advertised vehicle which is worth nowhere near worth this amount in this condition.
