The ϕ→γππamplitude is found from the e+e-→γππamplitude suggested in Ref. hep-ph/0606266. It is shown that the found amplitude differs essentially from that studied in Refs. hep-ph/0606266 and [3]. It is noticed that the suggestion of the author of Ref. hep-ph/0606266 about the phase of the ϕ→γππamplitude is misleading.
