The four-piece girl group found themselves in the sing-off alongside Bad Lashes in last night's show, but they avoided the boot after the judges' vote went to deadlock and producers reverted to the earlier viewer poll.
"Any criticism we're going to take on board now," promised band member Tita Lau, 19. "Because we were in the bottom two, I think now it's time for Girlband to up their game and we're going to step it up. We don't want to be in the bottom two again ever."
Marisa Billitteri, also 19, added: "We're going to make sure we get harmonies tighter and like Louis [Walsh] says to us all the time: 'Girls, just rehearse, rehearse, rehearse'. And hopefully if we do that, next week we're not going to be in the last two again. It's just a horrible feeling. It's really terrible."
The girls also admitted that they were devastated to see Bad Lashes leave the competition after bonding with the group at the house shared by the contestants.
"It's just too much to take," explained Phoebe Jay Lau, 17. "I mean, Bad Lashes were just our best friends and it's so hard to see your friends go because they deserve it so much as well. I'm so happy at the same time but it's just too much to take, seriously."
The X Factor continues next Saturday at 7.25pm on ITV1.
