Vodacom contract *******

I had a cellphone contract with Vodacom which was due to end on 31 August 2021. I called on the 1st of July to give notice to cancel my contract at the end of August. I didn't receive any sms or e mail to confirm my cancellation request. I called again on the 26th of August to follow up on my request, to my surprise I was informed by their customer service consultant that there was no such request on the system, upon insisting that that was impossible, he did a turnaround and told me he is able to pick it up but the notice period was for 2 months. Eventually he told me that my contract will be cancelled on the 1st of September. On the 15th September I was billed again for the very same contract. When I called, customer care contract cancellation dpt and gave them the Ref no. for my previous call, I was told that Ref no. Was non existent and there was no contract cancellation request. I was told to log a new cancellation request yet again. I feel ********** and this amounts to *****. I will NEVER ever enter into any contractual agreement with Vodacom for as long as I live. Vodacom is just a ****2😡
