Poor service, misrepresentation and just plain rude

I upgrade to a new contract around March 2019, not long after I realized I could not make calls to toll free numbers from my voice bundle. I ended up calling technical support twice to try and resolve this which they kept on making me enter some digits and restarting the phone - I just left it, it never worked.

I've had 3 sales calls from Cell C, which I complained to them about the issue, they couldn't be bother to try and help, neither could they direct me to the complaints department. It's funny that they ask me if I'm happy with their service, but when I complain they can't do anything?

Today I finally mustered up the courage to try again, this time someone actually managed to tell me these numbers are "special" and cannot be billed from my bundle? What? The previous contract I was on, never had this issue and this was never explained to me? Apart from that, I don't see why you can't just take this from my minutes which I have paid for already. Where is this stated in my contract, this was never communicated. I'm also quite peeved at the dude that helped me, he was quite rude and kept on telling me to just add money onto the phone. That's not the ****** problem, the problem is that this was not communicated nor resolved from the start.

Again, also just not being able to put me through to your complaints department is just annoying. I also would like to know what happened to the ticket I opened with support initially and why no one was bother to try and resolve it?
