Third time Simcard is faulty

<p>Good day, I have three Cell C contracts, and the last two contracts that I took out I had to replace the simcards three times already. Yesterday the one simcard stopped working again, which means we have to replace it again and pay the R100 transfer fee for the number to the new sim card. That is R400 for faulty sim cards in the last year. The sim card is never taken out, except when we put another one in to see if signal returned after placing a different sim card in (it did). I would like to know how it can possible be expected that we must pay this fee every time, only to pay again after a few months? </p>
