Refused to assist because of the way my voice sounds

Hi so I phoned vodacom collections today and the agent refused to assist me due to my voice sounding like a female, she called me a mam and I didn’t feel the need to rectifying her immediately because if she authenticated me she would’ve seen I was a male. Upon answering the phone I said she was speaking to Moegamant Raafiq but she continued to say how are you mam and I answered. After giving my id number she refused to assist me apparently due to vodacom privacy which I knew was bull****. Because every other agent assisted me before. The call was at 14:34 12september2022 I am disappointed and disgusted at the service recieved from a vodacom consultant because if what she did was right and correct then I would assume that vodacom doesn’t serve the LGBTQ community. My voice is my voice and I refuse to change it for any consultant. This consultant definitely needs better training or perhaps vodacom should educate me on there policy
