Vodacom is a ****ty network provider

I've had the worst with vodacom. My account was send to Hammond Pole Majola & I was told to pay R556.06 it was paid by the 05-05-20 then I called Vodacom on the 13-05-20 & a consultant which I only have her email address which is *** who assured me that the account will be closed in 30 days. Today I recieved a call saying I owe them R 293.01 because the account is still active, how the hell can that happen with the account that's supposed to be closed. Vodacom its a ****ty network with the worst customer service. They are a ***** & just wants to eat people's money, I was moved from one consultant to the other until the last consultant hanged up the call on me cause I wanted to speak to management & lodge a complaint cause I won't pay an account I closed
