Richardson had been quoted as saying that South Africa had been unable to stand up to "the big boys".
CSA Chief Executive, Haroon Lorgat said: "If he is indeed correctly quoted, his remarks come as a complete shock to us. For someone who was actually party to the 2014 resolutions to now make such a disparaging remark to CSA is frankly nonsense and insulting to us.
"The CSA Board had from the very outset realised how damaging the original proposals would have been to the global growth of the game and together with Pakistan and Sri Lanka had strongly opposed it.
"The CSA Board will always stand up for what it believes to be right for the game," added Lorgat, who also said that the CSA President will formally take up this matter with the ICC Chairman.
