Phone under warranty, gets lost at Telkom repair center

<p>I took my phone in last month for faulty speaker repair and the only communication I received was a reference number SMS, 4 weeks have gone by and still no communication. I have been to the store where I took it in and all they can tell me is that it's with the couriers and don't know anything more.</p> <p> </p> <p>The couriers and the Telkom Device Tracking Management divisions are not picking up the calls when called from the store to give a status update. Called the main call enter and they too can not offer me any assistance. My phone has vanished without a trace and no one has answeres for me.</p> <p> </p> <p>Where can I escalate this so that I can get my phone back or be issued with a new phone since this is a contract phone that I'm still paying for.
