BILLING AVOUNT

Got a problem with my cellc contract. want to take them to court. I stopped using their contract sim card because it disconnected all the time. Now they want me to pay. what am i going to pay for?. I had the cellc sim card. It worked on the bphone not once it did disconnect. So couldnt use the sim for to long. <br> Now I HAVE TO PAY UP FOR THE benefitts i didnt use. I didnt use. I called the collection company that is collecting for them. requesting a detailed statement for since it was handed over to them. They couldnt help me. I want a detailed statement and will pay for the phone not the benefits that come wit it. I refuse to have a bad credit record becaus eof them.
