Swop out unit 3-4 weeks!!!!

<p>I booked my Mobicel Plum Tablet in with PEP port Alfred who in turn booked it in with MTN HVRC on the 20/04/2017. Collection number M ********** . On the 28/04/2017 I spoke with Zandi at the HVRC call centre and was told it was "Awaiting Exchange". I phoned today 03/05/2017 and spoke with Lerato and Zarida and first got told it was awaiting fault identification because it was a swop out unit. Then got told by Zarida it was " Awaiting Exchange". 1 week and still not exchanged??? I want my tablet that is "Awaiting Exchange" or my money bac****!!!</p>
