CellC lack of serivce delivery

I am still struggling with CellC. This is now a solid month without any data coverage. I did an upgrade on 1 or 2 April 2019. At first I was not advised to get a new sim card. As I got home, I could not connect. After a marathon phone call, CellC said that I am supposed to get a new sim card. They will deliver one to me. I waited two weeks for the delivery. And then I was advised to buy my own, which I did. The operator even gave me his email address: as soon as I have the new sim card, I can email him and he will phone me back with instructions. I sent him three emails, and I am still waiting for ********** to get back to me. Then, when I communicated with them on their website, I was phoned again, and the person asked me some questions, RICA-ed my sim card and promised me that I will be connected within 2 hours. This was on Friday 26 April 2019. Needless to say: I have been paying for a data contract that I have not been able to use in the commencement thereof. I am not even angry anymore. I just can't ****hom the extent of CellC's inability. I am beyond angry. I am just totally powerless as I get no reaction whatsoever. I am stunned by CellC's incompetence and lack of client service. It really amazed me.
