faulty vodacom phone

e bought a vodacom prepaid cellphone from makro centurion 2 months ago, date was 30/09/2015. Samsung trend neo. After about 2weeks phone restarted during phone calls. Giving message unable to detect sim restarting. <br> We went to makro lavender road and they didnt helpus. They refered us to vodaworld.<br> <br> From november we have handed the phone in 3 times. That means driving to vodaworld to hand in phone and to collect.that is 6 trips of about 70 km both ways.<br> <br> We collected phone again on saturday. And again phone is restarting. <br> <br> I will not go to vodaworld again for this phone. We are so frustrated, i cannot explain it. Who will take responsibility? Makro that sold us a faulty phone or vodacom for nor repairing or replacing ? Is of funny to play games like this with us<br> <br> I want the money back for the phone or i want a replacement. Not a samsung. Im finished with samsung
