"Unfortunately, the Congress high command did not listen to feelings of Union ministers from Seemandhra, of Chief Minister N Kiran Kumar Reddy, state ministers, PCC president, MPs and MLAs," Rajagopal told reporters in Vijayawada.
Amid speculation here that Chief Minister Reddy may quit in the wake of Centre going ahead with bifurcation, Rajagopal said he urged him not to quit before February 21, when the Parliament session is slated to conclude.
Reddy, who has been opposing the division, staged an unprecedented sit-in in Delhi this week to voice the protest of Seemandhra Congress leaders.
Congress MP from Guntur R Sambasiva Rao said he and other Seemandhra MPs and Union Ministers would vote against the Telangana bill in the Parliament.
State minister T G Venkatesh said their decision on future course would also depend on the "note to be sent by President to Parliament".
