faulty sim card

My simcard stopped working on the 08th December, been calling the Autopage call center service trying to find a solution for my phone but with no help, this morning of the 09th December called them again they tell me my simcard is connected on their system the problem could be that my sim is faulty i need a new simcard. my problem is that how do they expect me to pay R150 for a sim card that i have never taken out since the purchase of the phone, its not like I'm the one who damaged the sim card. i find it very unfair that i pay for the phone every mouth now their sim is giving me problems i have to pay.<br> <br> please help me Hello peter.
