Never received data/billing -Accounts

<p>Hi, I have phoned the call centre regarding my account for March (bill so far for March) that i have been double charged for my Line rental (R 549-00) I have also been chaged for 10Gb promational data (R599-00) that should have been free when upgrading with Vodacom. I also bought 1G data on the 13-03-2017 I received 1G free data but never receieved the 1G I paid for (order number E ********** ). I would like this sorted out, i called the call centre this morning and was told its not the final billing for the month, and when month end comes it should be sorted, what happens if its month end and this amount still gets debted from my account??? Account number I ********** -7</p>
