Vodacom 30% matric staff

I have a lousy data contract with Vodacom monthly payment R214.97. Since a customer cannot cancel in a shop anymore, it is done online which I did 30 days prior. When doing so I received an sms that I would receive confirmation of cancellation, no need to say it never happened. Result, the *********** 30% matric staff from Vodacom did not cancel yet kept on taking money from my account...which I blocked obvisouly. Kept on emailing with staff, emails were read but not answered (having dozens of emails as proof). Phoned a couple of times the cancellation department, months down the line...still not cancelled. Also several calls were 'the system is not available', 'we have a system error' and so on. Now they handed me over to an attorney. That very same attorney does not read the email with all proof (another 30% matric that seems to be illetarate). In the banana republic of South Africa consumers have no rights! I demand in writing communication, not over the phone with empty promise they would take action. For that reason I don't even take contracts anymore and I buy my device overseas.
