I took my automobile to a mechanic to have the sparks plugs replaced . I belived he change engine in my automobile . what can I do?

Answer

What you "believe" does not matter. What actually happened is what matters. Take the vehicle to a reputable mechanic to see what, if anything, was done. Then deal with the real issue, if there is one. If the engine was replaced, it is time to see a lawyer.
