Vodacom Cancelations agent unprofessional and phishing for personal information

I called Vodacom to cancel my account that is paid up, but the agent on the line was pushing vodacom products onto me in such a desperate way. Even though I said no thank you she continued harassing me punting several products. My airtime eventually ran out after 17 minutes. The account still has not been canceled as I haven't received a confirmation sms or email.

The number I want to cancel is ***. The phone was ****** 2 month after taking out the contract and it's a relief to have paid it off, but now Vodacom is giving me such hassles.

Please help!!!!
