Disappointed, bad service, false lies....

I have been a long standing customer of Vodacom. My contract was due for an upgrade. I asked a few times, different people would I need to pay for both contract until my contract ends, end of July. I was told no. It's on recording aswell and I would only have to pay the handset till end July. Now I'm told I'm in arrears and I must pay my old installment aswell. What bull is this. U guys lie to trap people into paying more.... Now I'm stuck with the worst provider for the next 3 years. Shame on u guys
