Absolutely Appalled by Vodacoms service!!!!!

My LTE contract was due to finish in February 2022. In January I went to the store to cancel the contract and was told that I should phone customer care, after not getting through I decided to email customer care and after correspondence with a consultant, was told that the contract would be cancelled on 28 February 2022. This did not happen and I was billed for March 2022 so I emailed again and they took their time in responding only to tell me that I have a business WiFi contract and I'd need to deal with the fibre/LTE department, upon emailing them and waiting for a response, I was then told that it is the wrong department again and I was meant to email Vodacom business cancellations as it is the only way to cancel a business WiFi contract, there is no call centre number. Upon emailing them, I was then told that the contract would be cancelled on May 1st 2022 so I told the consultant that I have been trying to cancel the contract since January 2022 and would prefer the contract be cancelled on March 31st 2022, they asked for the email correspondence from January which I forwarded to them and I have not received a reply since and now I have been billed again for April 2022. I am absolutely appalled at the service, I had provided my Vodacom account number and ID in my emails so they had all my details from the beginning but why was I not transferred to the correct department and given the correct contact details from the beginning?! I honestly feel like this is just a scheme by Vodacom to delay cancelling the debit order. I want to be refunded for the extra months that I had to pay!!
