BOUGHT AT JET MART - RUSTENBURG

I bought an Hisense U602 on the 07/10/2015 and it started giving me problem sometime after the purchase and eventually it stopped working and couldn't read the sim card.<br> <br> I took it to Jet Mart in Rustenburg on the 03/11/2015 where I bought and they said they would book it in for some repairs. I has been two weeks already and I am not getting any feedback.<br> <br> I tried calling 3G Mobile who are supposed to do the repairs to find out how fair they are but no one is answering. How long should I stay without the handset???<br> <br> Jet mart is also not answering their phones. How does one conduct business if they do not take calls???<br>
