Ntsiki Mazwai came out guns blazing on Thursday morning after she received an email that was allegedly sent to her by Bonang Matheba.
In the mail Ntsiki is warned to not mess with Bonang and her brand.
The songstress was told to focus on her musical career and even called a "dog" in the email.
Bonang later tweeted at Ntsiki that the email was not sent by her.
How ever Ntsiki was not convinced stating that the email she received came from Bonang's account
