Horrible Experience

Im really not happy with the service received from vodacom. In march i was called by people saying they are from vodacom and was advised that my plan is no longer available and they will have to change my plan. When i checked i was changed to RED Flexi 550 monthly plan. Something which i didn't agree too. when i called vodacom asking them to change they said they can only change it after 3 months I waited for the 3 months when am calling them now, they're telling me that I have to call the reward line. On the 27 March 2022. A Case was opened, the very same day it was closed. nothing was done am still on that my RED Flexi 550 Plan. I don't want it anymore please revert me back to where i was before.
