Costs on account not told about

<p>Good day</p> <p> </p> <p>I was given a call in Feb about my contract, vodacom asked if they could migrate my contract from the Uchoose flexi 750 to the RED advantage because i use a lot of data and call charges, they said that it would cost me exactly R999 per month, first month i get an account and now there is an extra R333 for handset charge and vat and extra's. Today is the 2nd of may and my account for this month is already sitting at R1547.50. I will not pay this account until you remove all the extra costs from my account, and the same goes for the previous months where my account was R2500 and R2200.</p>
