Vodacom bully their clients

My name is Megan contract number *** I have been having problems with vodacom for a few months now there call centre agents have been of no help and every time I ask to speak to a manager there is never one around. I had requested in January for my contract to be cancelled which the agent informed me that end of January would be my final debt order . Then they still continue to debit me I have been calling in to correct this and every time another agent would inform me that they’d put through the cancellation. They say there is no record of me ever cancelling which you would assume as they say all calls are recorded.The call centre agents have even been hostile every time I call I’ve escalated the issue but still vodacom refuses to resolve my issue I am at that point of getting a lawyer and taking vodacom up legally I’m so tired of this and these agents which I’ve asked many times to send me my reference number have not done it once I’m disappointed in vodacom , never knew they were this bad at customer service
