INCORRECT BILLING FOR THE 2ND TIME IN A ROW WELL DONE VODACOM

On the 28th of December, I got incorrectly billed by nearly over a thousand rand. I raised my grievances with you and I was assured that going forward that there will be no incorrect billing on my account. Fast forward to a little over a month & I am yet again being billed an exuberant amount to add insult to injury I received correspondence that my account is in arrears. I have been making contact with this beyond useless establishment for the past 3 days to correct their wrongs, for three days I have been running after you, begging you to fix errors you created and every single time my query seems to be brushed under the rug. The agents running your Facebook account are beyond useless & could not care less to assist & have the audacity to tell me, a paying client to call them to have these issues sorted out. I was furthermore advised that I will be called at 9am, it is not 11am & nobody bothered. I have spent 3 days of my life being inconveneinced by Vodacom who cannot do something as basic as bill their clients directly. I want someone to immediately contact me to cancel this contract with immediate effect, you have wasted too much of my time, This sim card has been broken up and thrown in the garbage where it belongs along with this business. I WANT THIS CONTRACT CANCELLED TODAY OR HEADS WILL ROLL. I have sent you over 85 messages on facebook and the one response I got was "call accounts on......" you belong up there with the likes of Eskom as they most useless service provider in the country with zero customer service s****s whatsoever. Congratulations Vodacom, you have reached a new level of uselessness.
