Vodacom cancellations not done

On 22 July 2024 I asked vodacom to move my number and contract to pre-paid. It is payed up. They sent an e-mail: We have acknowledged that we have received your request. The process will be actioned in 24 hours. Your reference number is: EC-1TUA-2J06V7. After 38 hours I travelled to Upington to chek up on this at the store. The store told me it was not done. On 29 Jully I wrote an e-mail asking them when will they do this. They have not rep****.
