Blackberry Faulty

My husband took a contract with Cell c on 18 09 2015. This was on a Blackberry Z3.<br> On 19 09 2015 he noticed the phone does not ring and we tried changing the setting but could not change to a tone.<br> <br> On 20 09 2015 we went to the store where we purchased the contract from and after waiting to be attended to the consultant tried resetting the phone. after 45 minutes she realized there was a problem and asked us to return the next day.<br> <br> On 21 09 2015 we went back to the store and was told that the phone needed to go in for fault checking. We queried whether we could be replaced with a new phone as the phone was brand new from the box. we were referred to the contract and advised that the phone will be sent in for repairs which will take 10 working days. we were sent home with the sim card which does not work on another phone. My husband had ported his number to the new phone so now he is without a phone and cannot access his sim. I find this service totally pathetic and furthermore we cannot wait for the phone to be repaired. We are still paying for the contract although we are without a phone! Come on Cellc stop ripping us off!!!
