Double billing

<p>Got a new contract in january 2017 and vodacom has been double billing me for handset instalment since january. Been to the vodacom store and contacted the help line numerous times, yet everytime it is queried I get no help or means of resolving this issue. They said they would cedit me for it but no credit and they have stopped sending me invoices since they querries in february. This problem is placing me in a finacial problem as large amounts are being debited from my account each month that I have not forseen.</p>
