No Feedback & delay to Cancel my request

On 14th February i received a mail from Vodacom informing me of new Price tariff of Vodacom home internet LTE Price plan Number *** and the email was clear that if you not happy with price plan you can migrate or terminate your price plan at no cost . however you have until 30th April 2023 to exercise your options at no cost to you. I called on 20th April Vodacom customer care request a Cancellation and consultant requested to confirm my details and numbers. after i explain the reason for my call to Cancel my LTE plan because the Bundle they will be offering me is little for the full month it wont sustain me. the consultant promise that she will send the request to Cancellation department and i even asked her to transfer to Fiber dept to see wont i get a better offer with fiber. I was promised I will be send sms with Ref Number for my Request and they will call me regarding my request. But it past 30th April and nothing was done, and no one called me or send me mail on my request. On 5th May i called again do a follow up because vodacom is not keeping me updated on my SR or give me feedback. I was again promised to be called back regarding cancellation of my Router cancellation. Called again around 19th and given number for Cancellation and i called them request Cancellation and lady Promised me my request will be resolved with 24-72hrs for cancellation & Refund. Ref *** and i spoke to Sandile Bambo. on 20th May i was debited the instalment of R514.00 and which was not suppose to happen because my request initially happened on 20th April which means i was within the time frame to cancell my Plan. Time pass by and Nobody still don't care to give me update and feedback on my request. On the 1st June i called again Cancellation department for Follow up because it seems like Vodacom don't care about giving me feedback because I'm no longer important to them, I'm just a number. They told me that i need to give them proof that i called the dates i mentioned earlier, which was never communicated with me or keep me update on progress of my query. What makes me Angry is the fact that i always have to call Vodacom to enquire about my request for Cancellation because they never keep me posted on my query. I requested for the Manager of cancellation dept and i spoke with Amanda Ndlovu she's one of the Line Managers and she requested that i give her time for them to do their investigations. But what's sad is if i never called in when will they have started with their Investigations? She even Promised to Called me back later which was Yesterday to enquire if one of the ladies called me for apology, but it seems like she was just making me calm down because the call never happen and promised she will keep me posted with the investigations. So it Seems like Vodacom dont take their customers Concerns Serious and they dont emphathise with us while we have challenge with Vodacom. Because whatever complaint or query you have with Vodacom they wont communicate with you on the progress of the request, they treat you like a number, dont really value us as Customers. I have been loyal customer with Vodacom for 15 years, and this is thank you i get from Vodacom.
