Billionaire Warren Buffett on Thursday denied a published report that he wants "radical transformation" at Wells Fargo (WFC).

Earlier in the day, Douglas Kass of Seabreeze Partners Management wrote in The Street's Real Money blog that Buffett "expressed his extreme dissatisfaction" to the bank's board of directors and called for "a radical transformation of the bank's ethics, in no uncertain terms."

Kass has a small short position in Buffett's Berkshire Hathaway (BRK-A) .

A spokesperson for Buffett told CNBC that Kass' note can be reported to be false.

The Omaha-based billionaire previously indicated he wouldn't comment on the secret account scandal before November. Buffett's Berkshire Hathaway holds the largest stake in Wells Fargo with about 9.51 percent of shares outstanding, according to FactSet.

Wells Fargo was hit with $185 million in penalties for opening fee-generating accounts without authorization. Over a five-year period, the bank said, 5,300 Wells Fargo employees were fired over the practice.

Wells Fargo CEO John Stumpf told the House Financial Services Committee on Thursday that the bank will be eliminating all sales goals by the end of the week.

In July, Buffett applied for approval to expand his stake in the bank.
