Poor customer care

So until today nothing has been done to attend to my query? After calling countless times with consultants cutting my calls! Wow, and so i thought I was with the world's best network. Vodacom your consultants don't know their work and they unleash their incompetence on us when we demand answers. I want to know why is my statement saying I must pay R500 and something Rands when I'm supposed to only pay around R300. With even a moderm I haven't used nor connected. And please explain why your consultants doesn't want to give reference numbers for our queries? Because I had to literally demand for my reference from the last person I spoke to
