Cancellations

I've been trying to cancel my contracts to revert to prepaid all week.

I tried calling the upgrades and cancellations department a number of times, and each time the phone was put down when I selected the cancellations department from the menu.

I emailed *** and got an automated response.

I finally got through to someone in the cancellations department on the phone, and after chatting she promised to send me the cancellation quotation via email, which I have not received yet.

I then received a notification that my email query had been resolved, despite not receiving any further communication from Vodacom, nor any cancellation quotation.

Please assist me as I am unsure what else I can do now.
