Vodacom Contract cancellation

The accounts department deceived me by saying my contract will end in March, however when I call to cancel my contract they tell me different stories. One tells me my contract is left with one more month the other says it's finished but can't cancel the last one said this morning it's only going to end in September. Yeah, you guessed right I spoke to 3 consultants. They send me pillar to post without any assistance. The funny part is that, they are debiting me throughout this entire process. I don't know what to do now :(
