In this note, we underline that the proof of Hussain and Kanwal (Trans A Razmadze Math Inst 172(3): 481-490, 2018) has a gap. We provide two examples to illustrate our observation. We also correct the proof and improved the result by replacing a-admissibility by orbital a-admissibility.eninfo:eu-repo/semantics/closedAccessalpha-Admissible mappingsOrbital-alpha-admissible mappingsF-metric spaceFixed pointA Remark on "existence and Uniqueness for a Neutral Differential Problem With Unbounded Delay Via Fixed Point Results F-Metric Spaces"ArticleQ1Q1113431973206WOS:00048372590001711
