STAY AWAY!!!!

I am absolutely appalled by the service received from Cell C. I took up a contract in August. My Cellphones were delivered and no sim card. I have been paying a contracts for 2 months that i do not have the sim card for. i have spent about 500 rand in airtime phoning cell c over and over and over and over and now to be told to go and buy a sim card, with more money, then phone them again with more money as i need to buy airtime and then they do a sim swop over the phone. I have never received such bad service from a reputable company!!!!
