Rude and unprofessional consultant

Yesterday a lady by the name Nokubonga Mkhize cell number 0649819871 insulted me on my whatsaap after i told her she does not have phone manners because she called me with 0310107016 and when i answer she was laughing like a ********** and i told her she must call me back when she has phone manners. To my surprise she took my number and went on whatsaap to insult me with her cell number 0649819871. I have her conversation on my whatsaap where she was swearing at me and telling me she will bewitch me. I suggest the management of this company should teach their employees manners and their staff should not whatsaap us that is rude. Please remove my number on your data base because i do not want to be associated with such stupidity.
