After Sales Department Service POOR

I did an online upgrage with Vodacom and received my device yesterday, firstly there was no sim card in the box as it says in the list of things I am to receive from the service provider. Secondly the device is defective, switches on when charging but then goes blank after that and then the battery shows that it's dropping down rapidly.<br> I called the call centre and was told to contact after sales. Did that from literally 08h00 this morning until around lunchtime and couldn't get through. The phones just ring unanswered and no one at the call centre seems to have a clue what's happening. Went to the Vodacom Shop in Rosebank and all I got was a \sorry you have to call the after sales department". <br> <br> I need this device replaced and I need a sim card as promised. <br> <br> If none of this can be done then please cancel my contract and I'm not paying a single cent for opting out!<br> <br> Vodacom's service is pathetic! They charge exorbitant rates"
