False advertising Vodacom

I would like to share the appalling service I have received. I recently signed up with Vodacom under their advertising of fast reliable internet, this is indeed false advertising. After a while of back and forth communication between us, which they barely even seemed to have any interest in, they activated my line but only to find out that the package I signed up for I didn’t get, so I called in and was very calm giving out their errors and all I got back in return was scrambled information, no one really knows what’s going on and their, I was then given wrong contract information about myself from a call center agent named “Zola” after she realized that I had pointed out her mistakes and after me asking to speak to her manager, she immediately put me on mute and then a few seconds later hung up on me. I still kept a very calm attitude and called back in, then was assisted by a guy named “Dada” he seemed to want to help and took down my information, he also could see that Vodacom had somehow messed up with my profile and this obviously isn’t something they want the public to know so he assured me that a manage would call me within the next hour, after me asking him numerous times to transfer me to a manager which he said he could not do as he’s working from home. I waited the whole night up until now, no body has contacted me, I would also like to point out that the Vodacom QA department is also not doing their jobs, it’s quite clear that agents who mess up still don’t get their calls reviewed. I’m not sure what to really do now because my contact has just started off and there’s no service at all, so how do I continue with a company as such?
