Vodacom customer service poor and my internet connection down for days

Totally frustrated and disappointed at poor service from Vodacom. Call logged on Wednesday for internet service down. Had to call every day since, sent email to CEO for help out of desperation. No one that promises to call back ever does. Spoke to multiple vodacom employees and no one taking accountability. Being sent from pillar to post between vodacom and vumatel. I’m close to tears the way I’m frustrated and still exactly where I was on Wednesday when I first logged this fault. At my wits end and have no idea what to do next. All my efforts to engage with Vodacom has come to naught. What is next for me? I’ve done everything I needed to do as a paying customer and more. Please, help. I don’t know what else to do.
