Angry Customer, soon to be ex customer

I have been on the phone with Cell C from last week querying a pocked router I did not request for, i have been getting service numbers but they are unable to trace it first case ***, this was to cancel what ever SPI*** that was ordered against my name, so I call in again today an the agent tells me to log a call with *****, why should i do that if i did not request for it. I see the number activated was *** for this Huawei E5576. I will not pay for something i did not sign for because of Cell C and their agents who don't know how to cancel something that was not done by me.
