Follow up on my issue not resolved and bad service

follow up review. Last week Thursday I posted a review here about Cell C not wanting me to do a SIM Swap on my contract number and about increasing limit without my consent. Cell C responded and said one of their consultant will contact me to resolve my concerns. Last Friday I got an email from one of their Consultant ' Maropeng Motana' around 8 am saying he was unable to reach me on my cell (the number they refusing to do a Sim Swap for) and I gave him my alternative number. He called back at 12:06 asking me about my concerns and we agreed that he was going to listen to the intial call when I was offered Router last year August and promised to phone me back but until now I'm still waiting for his call. This morning I called him and after hearing that it was me he dropped my call and after that he didn't take my calls.

I am very disappointed with Cell C. the worse part is that i really need to use my phone. I'm ready to take a legal route because as much as they are not willing to solve this I can't even port to another network in the mean time.
