Cancellation of Vodacom contract.

My contract at Vodacom ends by the end of October 2024. I already contacted them two times, 19 Sept and 25 Sept 2024 by telephone, as well as drove to the Vodacom shops in Paarl as well as Stellenbosch. They are more interested in why I want to cancel and to give me other contracts than to, it looks like, to cancel the contract of ***. I just hope this is not a means to let the contract go on for longer. They said I will immediately receive an sms and a notification by email which I still did not receive. I asked for a ref number but said they will send this with the cancellation contract.
