NO IPHONE STOCK

My iphone is currently due for an upgrade and everytime i contact Cell C they have no stock and cannot even provide an ETA. My current Iphone has crashed and i urgently need to upgrade ASAP. I am not willing to change to a new device or software. I need someone at Cell C to atleast provide an ETA and not just keep giving me the run around. It's concerning how all the other networks have stock except Cell C, it's bad stock management on their part and they should be trying to outsource to keep their existing customers happy. If this isn't resolved soon i will be paying up my contract and moving to a new more reliable network.
