A woman allegedly raped and kidnapped by former Blue Bulls rugby player Phindile Joseph Ntshongwana promised him she would be a good girlfriend, the Durban High Court heard on Thursday.

"I told him I was going to end my relationships with my other boyfriends," said the woman, who cannot be identified.

Ntshongwana is charged with the murder of Thembelenkosini Cebekhulu in Montclair on March 20, 2011, Paulos Hlongwa two days later, Simon Ngidi the following day, and an unidentified man sometime that week.

All were hacked to death with an axe.

He is also accused of kidnapping and raping a woman on November 28, 2010, and assault with intent to do grievous bodily harm. He also faces two charges of attempted murder.

He has pleaded not guilty.

The woman was allegedly kidnapped by Ntshongwana as she was walking in central Durban, and was held for three days.

She said Ntshongwana woke her up violently on the third day asking her what she was doing in his room.

"He asked me why I killed his child, he said I had an abortion... [he] said I had killed his child by infecting it with HIV/Aids," she said.

Ntshongwana told the woman to choose between him and her boyfriends.

"He said if I didn't choose him, he was going to kill me," she said.

The woman said Ntshongwana told him she was supposed to be dead.

"I pleaded with him not to kill me. He told me he loved me. Because I did not want him to kill me I told him I love him," she said.

The woman asked Ntshongwana to take her home so she could fetch her clothes and he agreed.

While Ntshongwana was in the garage, the woman took a copy of his ID and a slip from Debonairs from his room.

When he was taking the woman home, he told her he would kill all her boyfriends so that they could live peacefully.

As the woman was walking inside her flat, she saw a girl carrying an exercise book and a pen.

She asked her to take Ntshongwana's vehicle registration as he was waiting, parked outside her flat.

When she got into her flat she asked her sister to call a priest.

The police were called in and the woman was taken to Addington Hospital.

The woman wept while testifying and cried profusely when she was asked by the State to identify her kidnapper and rapist.

She eventually pointed at Ntshongwana.

After the lunch adjournment, Themba Mjoli, for Ntshongwana, asked the court for a postponement.

Mjoli said Ntshongwana's parents had asked that he be observed as he seemed agitated, which was a symptom of his sickness.

Ntshongwana has been diagnosed with a bipolar condition and schizophrenia.

The matter was adjourned for Monday, but the woman would be only be cross-examined again on Wednesday, as she was writing exams.
