Terrible service from Cell C

I app**** for a fibre contract on 19 Sep 2018. On 3 Oct 2018 I got an email from Cell C Fibre stating that my application was successful and that the fibre company would call me and arrange to do the installation. SADV came to do the installation on 10 Oct 2018. Once done they said that Cell C would contact me to activate the fibre service. On 12 Oct I called Cell C and the guy did not even know what he was talking about. Saying that my 082 number is registered with Cell C. Meanwhile it is with Vodacom. He said he could not pick up my fibre contract. He said he would get someone to call me. The same guy called me back at 14h29 to ask me what fibre company I did the installation and I told him SADV but he said it had to be Vumatel. Then on 15 Oct, I got a call from Cell C who told me that they would send someone to come and deliver the Cell C router and give me username and passwords. They said I would be contacted and advised on when they will be coming through. This never happened. 22 Oct, I called Cell C where the guy took all my details and said he would get someone to call me. 23 Oct at 9h19, I got a call from a technician at Cell C and he advised me that the sales rep who helped me with my application was supposed to contact me and advise on when they will be delivering my router. I gave him their details and he said he would get them to contact me. 23 Oct 14h15, I got an email saying my fibre is active and had a username and password. I do not even have the router from Cell C so how can this be active? Then Cell C called me at 14h18 and I told the lady that I received the email and she said she would speak to the sales rep who helped me with my application.Also I have a wifi / data deal with Cell C which is running month to month and I need cancelled because I am now taking fibre. The sales rep was supposed to assist me with this as well. As I do not want to have 2 contracts running with Cell C at the same time and paying for both. I actually do not know what to say. I am beyond furious at the lack of service and knowledge that I am receiving from Cell C. I am not paying 1 cent for the fibre until I have received the router and I can access my fibre.
