This is despite a claim by Amal Nassif that she was blinded after being told by Zachey that she would able to see the Virgin Mary if she stared at the sun.
Speaking to the Sunday Times at her home, which locals called the "church", Zachey said she continued to be "God's vessel who changes people's lives for the better".
The 20-year-old said although she had not had any more visions of the Virgin Mary since 2007, her duty now was to "fulfil the message".
"I conduct prayer sessions with the help of a prayer team that comprises members of our parish community every Saturday from 2pm to 6pm," she said.
Her father, Frank, said between 50 and 100 people came to Zachey each week so that she could pray for them.
The family's home is decorated with pictures of Jesus and the Virgin, and the Zacheys have converted a room in their home into a gift shop.
The shop sells rosaries and prayer books, as well as R120 T-shirts that bear images of a tearful Virgin carrying a baby.
"One of my visions was of the Virgin Mary next to a mountain of dead babies. She was telling me to spread the message that abortion needs to end," said Francesca.
Father Barney McAleer, who heads the Department of Evangelisation at the South African Catholic Bishops' Conference, said Nassif's claims were never reported to the authorities, including his organisation.
"The Catholic Archdiocese in Johannesburg issued a statement some time back saying they hadn't made any pronouncements regarding Francesca. This remains the case. These things cannot be decided upon immediately and you can't be in a hurry to make statements or rash decisions," he said.
