No way of reporting potential *****.

I have been trying to contact a ***** hotline at Telkom all day to let them know that 2 individuals have been calling me with all my Telkom information and asking if I would like to upgrade to Fibre. They were well versed on the ADSL problems in our area and who the Fibre provider was. I indicated that I would be interested in moving but they tried to get me to send my Telkom account to them. If they are from Telkom why did they need it. They kept phoning from an 011- *** number and emailed me from ***. I am trying to get someone from Telkom to report this to but keep getting passed back to an unanswered number ***.
