Cancelled cell phones contract not effected

Hi Hellopeter, kindly assist me with regard to my cancellation issue with Vodacom. I had a I am still at Old Mutual, are you done koo???cellular phone contract with Vodacom which expired on the October 2023. In August 2023 I visited the Vodacom outlet at Key West Mall to notify Vodacom of my intentions not to renew my contract with them on expiry. A consultant there (forgot his name) advised me to come the following month being 1 month prior to expiry period. I went back to the same outlet on the 16 September 2023 to make the notification as intended and spoke to consultant named Brian, who advised I call thenumber *** as they do not do cancellations at the outlet. On the 18 September 2023 I called the number *** using the number *** and spoke to a consultant named Mphendulo about the cancellation. He tried to convince me not to cancel but I indicated to him my reason for the call was to terminate the contract NOT renew it. Finally he agreed to cancel the contract on expiry but to my suprise I was debited an amount of R 591.89 which I reversed as I knew that the contract ahas been cancelled as per my telephonic conversation with Mpendulo. On the 10 December 2023 you called the number *** and followed the prompts and was not successful.I was then given the number *** from one of the consultants at the same Key West Mall outlet. I then called the number and spoke to Keneilwe Baloyi who said she will escalate the matter for cancellation. Unfortunately again on the 19 December 2023 I was debited an amount of R 1 288.85 which I reversed as I knew that the contract has been cancelled. As I was near the Key West Mall Vodacom outlet I went in to enquire why am I being debited whilst I have cancelled the contract, the consaltant I spoke to then called to enquire. He gave me the phone and person I spoke to introduced himself to me as Tyson. I then asked him why am I being debited the amount of R 1288.85 whilst I have cancelled the contract since it had expired in October 2023. Hi response was that my contract was not cancelled by both Mpendulo and Keneilwe and thus when he effects the cancellation it will be only cancelled in January 2024. He further said he will escalate the matter for investigation to ascertain who dealt with instructed to cancel the contract of which if the fault lies with them they will have to incur the cost thereof. I would appreciate your assistance in resolving this matter . Kind regards Matshidiso Johanna Khoane ***
