Vodacom over charge again

<p>I upgraded my cell number (079 497 0 in the last week of Dec 2016 to flexi 110 from prepaid. </p> <p>I requested a sim only upgrade of R79.00 pm. I was advised by sales person my account will be billed prorata for Dec 2016 and I will be billed the full amonut in Jan 2017.</p> <p>3 days later my bank account was debited for R110.00. </p> <p>I called vodacom on the ********** number (13/01/2016) to rectify billing problem. I was transfered 6 times (cut off 3times) to different people, eventually i got a dept who said they are busy and i must try again later. I was told to call ********** 9 and got the same reply (busy, try again later).</p> <p> </p> <p>I have been with Vodacom for over 10 years and keep having billing issues with them.</p> <p> </p> <p> </p> <p> </p>
