Frustrated with Poor Service!

My Cell C Blackberry was taken to Game Parow Centre 7 weeks ago, The port where the headset connects to was broken, which I asked them to repair. It was sent to Cell C for repair.They kept my phone for 6 weeks and when I finally received it back, instead of fixing the port, they only replaced the screen ( which I did not ask for ) Now I had to take it in again! Am I now going to wait another 6 weeks and I certainly hope they not going to charge me for this inconvenience!
