fulgative , rude consultant

I have just received a call from a consultant by the name S Govendor she told me that she is calling from Elite Mobile part of Vodacom, she told me Vodacom has selected me to receive a tablet and airtime for R60 , she further asked me where to deliver that tablet , i gave her my work address and she also needed my home address , which i gave her . When she further asked me my salary i asked who gave her authority to evaluate me ? I asked her name and who did she report to and she used fulgative words on me . I need this to be attended to asap
