Centrifugal force (離心力) is, in fact, a kind of "psuedo force" or "inertia force". As contrast to a real force that exists in any inertia reference system, an inertia force only exists in a non-inertia system, such as one that is under acceleration.
Inertia force is a useful concept in physics. You cannot say that this concept is wrong, as one would experience such as a force in an accelerating system as if it is a real force.
