Charged for 20GB I didn't order

<p>I received my May account and I was charged for a further 20GB. I have a contract that includes 20GB which I have no way of ever running out of. I have never ordered the additional GB's - yet someone in sales has charged me for them. I have called in 3 times. I have 3 reference numbers and each time I get told "You dispute has been cancelled." I am not allowed to chat to a supervisor. I am not allowed to chat to Sales. But I have been told that someone in sales says I ordered this. SO I WANT SOMEONE AT TELKOM to contact me and to sort this out. My contract runs to February 2017. There is no way that I need 40GB of data and there is no way that I ordered this. This raises alarm bells for me as someone at Telkom is charging for items not ordered and this is *****. I am not paying for somethign I have never ordered. Look up my account on ********** 478 and see. Fed up and am so definately cancelling my contract as soon as it is up next year.</p>
