Voda

So I have been trying to cancel my contract from Dec and still in April the say I am going to be debited. My contract is still not cancelled and I am being told they have to investigate as they do not have trace. the note say in Feb I called to cancel. They have the notes to cancel but they say they can see a note it take 48 hour to investigate. Vodacom does not have a complaints department, that is what I was told.
