Vodacom is beyond useless and a bunch of *******.

I received and paid for an early cancellation on 20/02/2018. I had no response for 2 weeks until I took my complaint to Twitter. The account was cancelled and number ported before March. I was PROMISED no further monies would be deducted from my account. I still received a bill for the March period and had R1865.06 deducted off my account on 3 April. I have had exactly zero responses from ********** and the call centre just transfers me from person to person until I get cut off every single time. I have called 082111, ********** & ********** . I have taken my complaint to twitter again and get no help, just promises of escalation. I can't get through to ********** because it says I don't have a valid Vodacom number. NO ONE WILL HELP ME. Vodacom has ****** my money!!!!! Can you understand why I wanted my contract cancelled??? This is unacceptable! I even put a stop on my account (which I had to pay for) so that vodacom could deduct no further amounts and they still managed to *****.
