Vodacom does not want give phone as per contract

We submitted a report on HP with regards to our broken BB 9720 which they deemed beyond economical repair. A Vodacom agent promised to investigate and return to us. <br> <br> We are aware that the BB9720 are prone to breakages on the charging unit which proves the breakage was not our fault How can we be held responsible for a common breakage known to the company . <br> <br> It has now been weeks (23 March) with no response. It appears that Vodacom does not honour their promises. Is it because you do not want to replace the phone as per your contract? Again we have 4 contracts with Vodacom and 2 pre-paid phones and we will move if we start finding that Vodacom is no longer the company for us. <br>
