Unpleasant Service

Cancelling my Vodacom contract has been a nightmare!! Vodacom service is really appalling. I have 2 contracts with Vodacom - 04/12/2021 I spoke to Phumzile to cancel BOTH my contracts effective 31 Dec 2021 and move them to prepaid. On 06/12/2021 I spoke to Noluthando to confirm if everything is in order. She confirmed both contracts will be cancelled. On 31 Dec only 1 contract was cancelled. I called again on the 31st and spoke to some lady who said my contract will move to prepaid Midnight - Nothing happened. On 02/01/2022 I called again and I was told the cancellation was not processed and they will process it and pass a credit. On 12/01/2022 I spoke to Wendy who told me she doesn't know what's happening and will get someone to call me and I'm still waiting. Can someone more senior and who knows how to do their job get back to me ASAP.
