Worst network ever!!!

I paid a premature cancellation only to be debited a so called difference which is apparently generated from an invoice with a different amount to my cancellation quote. So after speaking to 12 agents from different departments, being put on hold, being rude to, misunderstood, not heard, Vodacom tells me they not reimbursing me for what they made an error on. No consultant mentioned that I will still be debited after I pay premature cancellation fee after I asked a couple of times. Why tell me my contract is cancelled if you still going to debit me? What is the purpose of settling or canceling a contract if you still going to abuse my account? I want my money or I will reverse this unauthorized debit and escalate further. My perception and respect for Vodacom has dwindle down and I will definitely spread the word.
