Vodacom cancellations

Dear Vodacom Head of Customer Services, I am at a loss as to how else to ask. I wish to process a cancellation of my month to month contract. Yes its a month - month contract and I have battled for some time to cancel this.... My actual contract ended more than 12 months ago... Let me explain the challenges experienced to date (all recorded per your call centre agents). 7 Jan 2021 - call centre request to cancel current month to month contract and convert number to prepaid (recording confirmed). Agent attempted a retention strategy. Mid Jan - request to cancel once again - Agent confirmed that this would be done and final debit taken 1 Feb 2021. no communication from Vodacom since. 21 Feb - call centre agent (Jerome) again confirms this contract will be cancelled (cannot state why is hasn't happened yet and unfortunately cannot refer us to a manager at the time). assures us that the matter will be escalated for immediate cancellation and a manager (Chris) will call us. 22 Feb - Contact call centre once again (not contacted as promised), only to be told that Jerome did not initiate cancellation on the system, but it will be done again (agent - Precious) 23 Feb - contact call centre once again (Thobile), now unfortunately Thobile received the brunt of our frustrations over this period but even then, wished us away and wanted to send an email to her managers instead of processing the cancellation. Until this point no comms regarding the cancellation has been received. On more than one occasion during this call, we asked to speak to a manager or someone who could confirm the date and time that the cancellation would take effect from. This proved to be a difficult question to answer and eventually were told 24-48hours. After asking Thobile to speak to her manager, she simply declares, 'you cannot speak to my manager, my manager is too busy.' During this call I received an sms indicating that the cancellation is not confirmed until I receive an email/sms with this exact date - what's the point Vodacom? So here we are, reading all the similar posts online regarding the same challenges with cancellations. I do wish for yourself or your CEO to experience the call centre themselves and explain how this level of service is deemed acceptable for the rest of us. A call centre - Where managers are too busy to revert to customers and call centre agents are so empowered they disregard a customers request time after time.
