Cellc WiFi contracts

I recently put cellC on hello peter and with in a few days a consultant called me to resolve the matter of me paying for a WiFi + router contract yet I can’t use it because the router was not delivered since the day my contracted was approved and that October 2017. I called them immediately asking where’s the mobile router and they said they had to put my through to the consultant that helped me with the contract. They put the phone down. November I call and same thing happened. December I called to cancel the contract because I’m being billed for something I can’t use and they said they will cancel it but they billed me. February it was supposed to be canceled already they billed me and March. That’s when I came to hello peter. The consultant promised that it was sorted and I got replies on my previous review from cellc stating that it’s sorted out. The problem I have is that they keep debiting me on a account that I do not use so it goes into a negative balance and then I have to deposit money into my account to bring it back to positive, so basically by me doing so I am paying for something for the last 6 months that I could not use. I don’t think that is appropriate because I payed R1200 for something I can’t use. I called Trisha from cellc she said she would call me back but never.
