Vodacom - Unacceptable service

So as a service Provider, the services are rendered efficiently and mostly without problems. Unfortunately when speaking to consultants, it seems that none of them truly understand the system and how the various departments interact or they are just not capable of explaining it in layman's terms to a client. And when all is said and done, they just promise you that the matters will be resolved and it never is.

So cancelling fibre (this started mid April of this year) which is now an upgraded line, for which I was not only billed the full amount previous month, but I am now billed an additional pro-rata fee above the fee that was already paid for the month and despite having cancelled the fibre services to be effective at the end of June (which was by the way a month and a half notice) only to now be stuck with another line speed and the fibre services still not cancelled. In total there was about 10 consultants that I spoke to on the call centre in the time that I have tried to get this matter resolved.

Then after calling to confirm cancellation, and being told that it has not been cancelled, I was told that all audio recordings would be reviewed within 72 Hours to determine outcome. So tomorrow will be 7 days, never mind 72 hours, and this matter is still pending with no feedback. It is absolutely unacceptable that we should be held to the incompetence of the staff members that were supposed to sort out the query and get charged double on top of all that. And still the fibre has not been cancelled!!
