Cancellation of contract - impossible?

CANCELLATION OF CONTRACT

It seems like an impossible task to cancel a contract at Vodacom. I called to cancel the contract. End of the month – another debit order goes from my bank account. I cancel the debit order at the bank and get fined by Vodacom? Every day afterwards I receive calls from Vodacom telling me that my account is in arrears.

I called various times and spoke to different people on the 082-135 number.

I am unemployed and can not afford to keep the contract going. I need to migrate to prepaid.

To what extend must a customer go to get service?
