Shalafi, we live in a global community now, where everything that is said , anywhere is always available for quotes and commentary, is posted on the internet, is picked up by web crawlers, is made known of instantly the world around. If he did make such a comment, the mass media and especially the hundreds of F1 sites would picked it up, talked about it, attributed the quotes to the original source, referenced the comments etc.
If I am able to read about comments the Force India boss has said to a local Indian paper, then surely a comment by HK expressing anger over "not being allowed to race" would have been a headline in at least a dozen media outlets.
