The musical group wowed the judges with their performance at the weekend, then as a five piece.
But they've since lost a member having only been together for six months before their appearance in front of the judges.
Cameron has left the group for "personal reasons" with Rodney, Thomas, Julias and Elias carrying on together as a four.
“We were a five piece before but due to his own personal reasons Cameron decided not to continue with the group and we have to respect that," the group said today.
They told The Sun newspaper that Cameron's exit has brought the remaining four of them closer together.
Vox Fortis added: "We’re very strong, adversity and things like can bring groups together and I think that’s what it’s done to us.
"We are so together as a group now and I think there’s nothing we can’t do."
Right now the musical group are waiting to find out if they've made it through to the live semi-finals later this month.
Speaking to the official BGT website at ITV.com, they said it would be "a dream come true" to perform for the Queen at the Royal Variety Performance.
Elias enthused of their experience so far: "It’s been the most unique, magical and surreal journey and I don’t feel like my feet have actually touched the ground since we started and I don’t intend for them to."
Britain's Got Talent 2016 continues Saturday night on ITV.
