Worst network ever.

Cell C honestly is the worst cell phone network I ever had. 3xcontracts by them and so sorry I ever joint them..2years of bad signal, calls being dropped, poor Internet signal,being ****** of my sms's, adamant call centre agents and then when you want to leave them they hold you with there 30day cancellation rule.! They can phone you to sell you more contracts and up grades, but cant let you know your contract needs to be canceled 30days before the due date after I told there agent to make a note that I wont upgrade and is canceling,2 Months ago when he tried to have me upgrade.Then the cancellations department tell me they will give me a call back and guess what 4days later NO CALL BACK..what a surprise.
