Former world number one Simona Halep has accused tennis' doping authority of "publicly stating one thing while privately doing another" by requesting a further delay to her hearing.
Halep was charged with a second doping offence last week over "irregularities" in her biological passport.
The Romanian, 31, has been suspended since October after testing positive for a banned substance at the US Open.
The second charge is separate to the one for which she is already suspended.
In a statement on Twitter, 2019 Wimbledon champion Halep said the International Tennis Integrity Agency (ITIA) had requested a third delay.
