Phone still not working after 2 attempts to repair

I booked my Samsaung S4 in for a damaged screen and phone not reading the sim card about 3 weeks ago.The phone is still under warranty.<br> I got the phone back and it did not read the simcard.I booked it in again 3 days ago and received it back this morning ,still not working,but the technicians' report says its fine.<br> So I booked it in again demonstrating to the consultant it is not working and that the simcard is working fine in another phone.<br> I tried to call vodacare since 12h00.They answered the phone the first time at 13h50 after which the girl is walking around and trying to find someone to speak to me,but everyone is sending her to the next,speaking in Afrikaans which I can hear every word at the back.Then I get cut off.<br> Please just repair my phone or change it.<br> please teach your staff what it means to be professional.
