ASSISTANCE REQUIRED URGENTLY!!!!!!!!

I am really having a horrible experience with CellC, my cellphone was due for an upgrade. I have upgraded it and taken a laptop, although some genius who Assisted me with my upgrade changed my current cellphone number to a data sim. I have been requesting them to change it back but they want me to wait 3 months and I must pay some fee and cancel my upgrade, I didn't do the damage so why must I take reponsibility of such nonsense and go through such. I cannot make emergency calls or receive emergency calls. Can somebody assist me urgently!!!! I'm not going to keep calling the callcentre and be put through to 10 different people explaining my scenario.
