Not feedback and still being charged.

I requested in October that my Getmore247 service with Cell C be cancelled. I was told it will be cancelled end of November. However when I received my bill for December I saw it was still being charged. I then called on the 15th and requested once again that the service be cancelled and that the charge be removed from my bill. I was then told that they need to contact cell c as I was incorrectly charged in June after I signed up and that they will get back to me and that someone would contact me in 24 hours to process the cancellation. I still haven't heard back from anyone and when I called again today I was told that the case was escalated to the supervisor who was not there at the time and when I asked if the service was cancelled the consultant said it was still active. I am extremely unhappy with this service and lack of assistant! I want the service removed from my account immediately and the charge for December removed from my cell c bill.
