3 Sim card changes in a year and a half

<p>Truely pathetic, after 3 sim card changes in a year and a half, my wifes sim has once again stopped working. </p> <p>The local Cell C shops is adament there is nothing wrong with their sim cards. . but the results speak for themselves ....the sim just stops working ..forcing her to pay for a sim swap..althought its their ****** sim that stopped working...unless they want to blame Samsung's S3 and S4 mini...i dont see how it can not be the sim card.</p> <p>Tried for over 30min just to get through to a customer care agent ..and nada ...only the ****** irritating tune plays..</p> <p>She will be switching service providers.</p> <p>Just thought to let people know to stay the hell away from Cell C.</p> <p> </p>
