Day light ******* from Vodacom

I had a vodacom contract that was to expire last year December. They called me for an upgrade in November and I told them that I dont need it any more, I would like to get it cancelled at end of the contract.

They told me to cancel it on following month, I called them on the 20th of Dec and it was cancelled and they told me that my number will be migrated to prepaid. They also gave me a reference no for the cancellation. On the 31st they debited an amount of R320 instead of R130.

When I called them to inquire they told me they made a mistake and they will pay it back into my acc of which they never did. I then went to my bank, reverse it and paid R130 into their bank acc.

In January I got an invoice that I need to pay an amount of R840. I called them and they told me that the contract was not cancelled. I gave them the reference no, guess what? They told me that they see on the system that I cancelled it on the 20th of Dec but it was not cancelled so I must call the cancellations dept which also sends me from Pillar to post.

They told me I need to call collections and when I do they also tell me it's a cancellations dept matter. So I'm being send back and forth. I sent a complain and I never got an correspondence or a call for that matter. When I call to speak to the seniors they told me that they will listen to the call and revert back at me. Nothing

I still get those invoice to this date. Please help.
