Sowetan understands that the petite beauty, who is also studying business management at the University of Johannesburg, shot her last scenes on the show last week.
Sithole is believed to have fallen out of favour with the production team after she was allegedly not paid in December and started asking questions.
Muvhango publicist Amanda Ngudle said: “Bontle is a good actor and a great person. However, her character was killed off for operational reasons.
“She is at a critical stage in her university life and we didn’t like that her schooling was being affected by [her] acting scheduling.
“So, a collective decision was made and she was made aware of it and she didn’t object to it. We wish Bontle all the best with her studies,” Ngudle said.
