Rude employees at Vodacom

The lady working at the Vodacom Forensic department call centre on 07/10/2021 is very rude and does not know how to speak to clients. I asked her for her name and she refused to give it to me, she hung up. She raised her voice at me and hung up. Now I’m trying to call again to ask to be transferred to someone else or her manager and no one is picking up. This is on their *** number. I have been using Vodacom for 20 years and this level of disrespect is very new. Please speak to your staff.
