worst service for new customer

With me being a new client to cell c I thought it would be better than all the rest but this was NOT the case. Having only had my contract for a few weeks I already experienced how plain rude and time consuming it is trying to resolve a problem. My phone was ****** and I blocked the sim at the store after getting a new sim and pjoning the call centre to activate the new one they said that it would be active within the next 1-4hours but will be informed by a call! This is now 19 hours later no call no working sim. I called again, they give the impression they are doing you a favour by answering the call and helping, when you want to rate the service there is a problem and I should end the call on my side!!!!!! This is rediculous, although on time the debit order was deducted but no service is being received!
