*** Cancellation staff member misinforming clients!

On 12 July i called *** to port my number to prepaid from 1 September 2019, as the contract expires on 31 August 2019. Spoke to Leandra, who said that I cannot give notice at the time, and need to call in on 1 August 2019 to give notice, as the system wont allow it. I then asked for a reference number of which she refused, stating that she did not action anything, despite me telling her that I need a reference for her confirmation of what she said. She refused. I then hung up and called again and spoke to Patricia, who actioned my request. How is is that Vodacom consultants are misinformed and misleading clients? Thankfully this will be the last i interact with Vodacom. Hello MTN!!!!
