Vodacom Data Fiasco

<p>For 2 years the account mentioned's bill was R44.99. It was time for a upgrade and i upgraded it online, on the 11th Septermber 2016 to a R99.00 500mb data account. Nothing was mentioned that it is a open line. </p> <p>Not once. End of December i got my bill and it was R15770.35? No notice was send. </p> <p>I have phoned Vodacom customer care, and all they could say was it is a open account. I went into Vodacom shop, the lady at the counter also told me that die upgrade was a open line. But when I upgraded they should have told me that it was a open line an no one had said nothing. </p> <p>Why do i pay R99.00 for a 500meg and then keep on billing me thousands of rands. I am only working for a sallary and i am a loyal Vodacom client, always paying my account in full on time. No i have to make a lone to pay a vodacom bill that is totaly unaceptable. PLEASE HELP? </p>
