Cellc takes and dont care

I have two data lines with CellC, I received a call asking to upgrade because the 1 I have has changed. I told them I am not happy with the offering right now and she tried to get me to go onto another deal. I said I would like to cancel then she said she doesnt do that. I asked to be transferred to the right department then she put the phone down. These cellc people and company only know how to take money and not help. I even tried cancelling a line in store at Bluff branch and they said they cant help or take an instruction from me because it was weekend
