Vodacom ******** me 100.88 every month

I have been with vodacom since I started working in 2015. But the service that I get makes me hate them. I just wish I have money to close all the accounts that I have with them. I pay them on time every month but they decide to charge me 100.88 every month, when I call and ask for clarity they send me from one place to another. I really hate vodacom they're bullies.
