No feedback for a month on original querie

After my initial report below (5 November) I have sent SEVEN emails to no avail, NO response! I am fed up and want feedback! The level of service I am receiving is pathetic!<br> <br> I upgraded one of my Cell C contracts in December 2014 (telephonically - to save on the instore upgrade fee), the phone was delivered and I was happy. About August the phone started randomly going off and requiring charge more and more often, I battled on until about 3 weeks ago when I managed to borrow a phone from my parents and send in my 10 month old Blackberry. Today someone from my nearest store, where the phone was sent in from, calls and says the phone is beyond economical repair... It's confirmed that I haven't damaged the phone, no fault of my own (I assume it is a software problem) BUT they can't help me! So now, I am in a position where I will have to continue to pay for a phone, that's clearly faulty (as I can't damage software and internal electronic stuff), for the next 14 months... Very upset and feel the service and solutions are non-existent! The stores advise \try the call centre"- this is pathetic! I want this faulty piece of ******* phone replaced or at worst repaired!<br> """
