Vodacom4U-Highveld mall

Last year I was assisted by a guy by the name of Sfiso Manana in Vodacom4u at highveld mall in witbank and the guy almost assaulted me and after this was reported management never did a follow up on the incident I even sent an email to the regional manager as this was a concern and still nothing was done to address the complaint. The recordings of the incidents are there and the store also has cameras but nothing was done to disclipline the staff member
