Vodacom Contract Cancellation Nightmares!!!

I went into a Vodacom store to cancel a contract under my name and ID up for renewal. I was told that if I want to cancel any contract/ number I had to call *** they cannot do it in the store. The person in the store explicitly told me to make sure I get a reference number; else the contract is NOT cancelled. I called *** on 15/3/24 to cancel a contract in my name. The lady told me I don't get a reference number but will bet a SMS and an email confirming the cancellation. By 20th March I had not received any confirmation via SMS or email. I called *** again, only to be told that the cancellation was not executed by the operator (BUT ALL CALLS ARE RECORED????) HOWEVER the new operator said he will execute it for me. He gave me a reference number (which has NOT been confirmed by SMS or email either as he comitted), but informed me that Vodacom's policy on contract cancellations are to convert them to a "pre-paid contract"?????? I told him I wanted the contract and number removed from my ID number; he told me he will transfer me to a manager to discuss this as he cannot do this???? I was transferred back into the normal *** call center routing!! SHOCKING behaviour!!! This is *****!
