MTN NUMBER *****ULANT

I would like to report this number she kept on calling my 75 year old mother who is in rural areas putting pressure and **** to her that she won a phone as she has been buying lots of airtime, so she must go to pep cell to collect the phone, only to find out she is lying , when we call the number she is not answering but we can her picture on whatsapp, my concern she is not aware of such idiots she got excited and what next is she going to do, I'm so irritated with this girl.
