Total messup of upgrade.

I previously wrote a review about my furstration and very bad service by Vodacom. Needless to say after almost a month no possitive outcome. Vodacom made a total mess of my upgrade in November 2023 and changed my private phone contract to a data contract, instead of upgrading my data contract with a black friday special. On 31 December 2023 they nancelled my private phone contract and made it a data contract. I contacted every number at Vodacom and emails. Promises that everything will be corrected in 72 hours. It is almost end of month and they are charging me for a service i did't received. I am at rope's end and don't know what to do. Maybe you can help? Please. J. C van Rooyen
