Rapper Kwesta has been left feeling frustrated and angry by a rival's attempt to "sabotage" him.
The fraudster's efforts to gain control over the number apparently failed, after the service provider called Kwesta to report the suspicious behaviour.
"The sim swop stopped all communication to Kwesta's number and so we asked Vodacom to not allow it and to block any requests to do a sim swop over the phone," Kwesta's record label boss Nhlamulo Baloyi said.
Kwesta apologised to fans for the incident and claimed that it was an attempt to "sabotage" him.
