This paper contains our comments on the work of the authors A. I. Ahmadov \textit{et al.} "Single meson production in photon-photon collisions and infrared renormalons" [arXiv:0911.5226v1 27 Nov 2009]. We draw attention to errors made in this work in calculation of the subprocess cross sections within the frozen and running coupling approaches, in deriving the Borel transforms and Borel resummed expressions for the cross sections in the running coupling approach. We show that the same fatal errors were made by these authors also in their work published in Phys. Rev. D80, 016003 (2009).
