Mislead when calling to cancel a contract

Mislead when calling to cancel contract: I have been a client with Vodacom for very long, but after the last few weeks Vodacom might be losing a longstanding customer. On the 26th August 2025 I called to cancel my one contract and I spoke to Nkosi to cancel the contract, Nkosi informed me it takes 30 days to cancel and for me not to pay the huge amount he can assist me with a month to month contract of R700 and then my bill will not have the old contract price in.

On the 6th September 2025 I received my invoice and found the old contract price and the month to month added on my bill. I was upset and called the call centre to speak to Nkosi and an agent by the name of Stephanie spoke to me an and I informed her I spoke to an Nkosi and she said she does not know him, but she can see on the system I spoke to him and unfortunately he added stuff and never cancelled the contract, I told her this is wrong, because I told him I want to cancel the contract and he then said he has a solution form me so that I do not pay the old contract, but a month to month contract as it takes 30 days to cancel. She further informed me she needs to do a new cancelation of the contract, but it will now only be the end of October as it takes 30 days. I informed her this is not right and why must I pay another 30 days to cancel the contract, she explained to me she has to cancel the contract, because it has not been cancelled and she will be escalating my complaint as to the fact to the relevant people to investigate, because I am not happy as I called to cancel on the 26th of August to cancel teh contract and now I have to pay for an additional month, because I was mislead and the contract not cancelled. Since I spoke to Stephanie who I would like to commend, because she really did try to assist and even apologised for the inconvenience caused by Nkosi, I believe she did remove the stuff that Nkosi loaded, but this does not resolve the fact that I did call at the end of August to cancel and was mislead and now I have to pay for another 30 days extra due to the fact the cancelation was not done. Nobody has even contacted me since Stephanie escalated the issue to be investigated and still this is no positive outcome. There is only frustration and dissatisfaction and the possibility of losing a very longstanding client due to this issue. I hope this will be investigated and a positive outcome received, because this will determine if I still remain with Vodacom as a client or not.
