In this note we show an error in the proof of [1, Theorem 2.3]. Then we give a counterexample to show that theorems for cyclic quasi-contractions in [1] are not true. Also the proofs of theorems for cyclic strongly quasi-contractions in that paper are not true. We also state the revisions with modified conditions for main results in [1].
