The BBOG has championed the course for the release of over 200 Chibok schoolgirls who were kidnapped in 2014.
The girls who had spent over two years in captivity were reunited with their parents on Sunday, October 16.
Pulse learnt that since their release, no member of the Bring Back Our Girls (BBOG) advocacy group had seen the 21 Chibok girls.
Their BBOG group has been sitting daily at the Unity Fountain, Abuja to demand the rescue of the over 200 girls who were taken from the Government Secondary School Chibok, Borno state.
"The federal government needs to know that no Nigerian is more Nigerian than any Nigerian," said Aisha Yesufu, co-convener of the BBOG.
"They must know that the primary responsibility of government is the protection of lives and properties," she added.
The group had on several occasions been denied access to the Aso Rock Villa to seek audience with President Muhhammadu Buhari on the release of the girls.
Buhari had promised to rescue the girls shortly after he resumed office as Nigeria's president. The delay in achieving this goal led to friction between the BBOG and the federal government.
Most members of the group have sighted this as the reason why they have been "sidelined" on issues regarding rehabilitation of the 21 girls who were released on Thursday.
"Basically, the government has not allowed us to see our Chibok girls. I think like someone said earlier, the government is just being petty and behaving like a spoilt baby," Aisha told Pulse correspondent in Abuja.
"So because we (BBOG) have been demanding over and over, now they (FG) have the girls, they won't allow us to see them.
"But for us at BBOG, the most important thing is that the Chibok parents were reunited with their daughters. It is important that they get the right rehabilitation and psychosocial therapy and ensure that they go to school and acquire education," she added.
Meanwhile, The Islamic State-allied faction of Boko Haram which last week freed 21 of more than 200 Chibok girls kidnapped in April 2014 in northeast Nigeria is willing to negotiate the release of 83 more of the girls, the president's spokesman said on Sunday.
