Pathetic service yet again from Cell C

Trying to block a sim card and phone as my husband just got ****** and receiving such pathetic service from the call centre. My husband just had a breakdown in PMB, while waiting for assistance from his company, he gets ******. Phoning the call centre is a total waste of time, seriously, because we cant remember when airtime was last loaded and for how much, they cannot block the sim card or the phone yet i have the imei number.<br> Now we have to wait until my husband gets back from PMB, find an ATM and get a print out and then call to get assistance. That phone is only used for BBM, how on earth must we remember immediately after being ****** exactly when last we recharged and for how much.<br> The agents so are useless, this is not the first time we have had a problem with Cell C and don't even emphatise with you
