Poor service

I did and upgrade over the phone in JUNE,clearly told the sales lady that I wanted I top up as I have been with vodacom for more than 10 years on a top up contract. She confirmed it was a top up and so did her manager, now I'm being billed, I can't afford to stop using my phone as I use it for business, now the bill is running up, I called cancellation department 3 times and no luck ,I keep being pushed to different people, I asked for a team leader to call me back,it's 1 week now No call ! I asked for the call recording ,I still haven't received it, I spoke to Jewell from the cancelations department on my last attempt to resolve this matter and he gave me a number to call Elite mobile and said he was also sending them an email(The number he gave me doesn'tgo through).... that was on the 25th ...still no luck ... Vodacom has seriously dropped service level and it is disgusting...they ready to push the queries onto someone else instead of solving it.... Now I would rather port my number to another network
