Vodacom stop *****ing from ME!!

For two years you have been dedcuting money off my account for 2gigs of data that i requested as a value add on my existing contract. Instead your stupid call centre consultant created a new contract for me that i was not aware of. I only noticed this when i saw i get two debits from Vodacom one for my cell phone contract and one for a data contract that i never knew i had and that i never asked for. i tried to call you i tried to mail you i tried the walk in centre, everyone as useless as each other - for months now i've been trying to get this resolved and in the interim you just keep taking my money for something i DONT USE DIDNT ASK FOR AND DONT WANT. GIVE ME BACK MY MONEY...why do i have to go to these extremes to get decent help from your company??? YOU GUYS SUCK. I miss MTN....if it wasnt for the Nashua mobile swap i would never ever have been with you. I cant wait for my contract to be done with so i can give you the boot ...even Cell C is better....i wonder how many clients you'll lose with their buy out option...i know i am keen to spread the word. And please whoever responds to this...make sure you know your stuff...because i am tired of your incompetence.
