OUT OF BOX FAILURE

Good day<br> <br> About two weeks ago i took out a new contract for a Samsung S6, the handset had no faults besides the fact that it could not connect to network. The store tried to do a sim swap thinking that the sim card was at fault and that was within 3 days of receiving it. Then i tested the new sim card and it still did not work in different locations.<br> Then i troubleshooted the phone and tried inserting a different service provider sim and that still did not work which clearly states that it is the handset that had a problem. I took it in within 6 days of receiving the phone to the store, it has been 11 days and still no communication, i haven't even received a job number or any information about the device instead each time i go to the shop i get told that the system is offline and they are waiting for response from the repairs dept whereas it should have been replaced. Really poor service
