UNABLE TO REPAIR/REPLACE FAULTY HANDSET

I LOGGED A COMPLAINT THE 18 TH OF NOV, NO ONE FROM VODACOM HAS CONTACTED ME. MY HANDSET IS FAULTY, I REQUESTED A NEW PHONE AS IT IS MANUFACTURER FAULT, BUT HAD TO TAKE THE PHONE IN FOR REPAIRS, THE PHONE CAME BACK STILL FAULTY, I HAVE TO SEND IT IN FOR REPAIRS AGAIN. THEY ARE FIRST OF ALL SENDING ME FROM ONE DEPARTMENT TO ANOTHER, EACH ADVISING ME THAT THEY ARE UNABLE TO REPLACE THE PHONE DUE TO FACT THAT I HAVE THE PHONE ALMOST 3 MONTHS AND IT IS UNDER WARRANTY. THERE IS NO TECHNICIANS IN PHALABORWA, MY PHONE NEEDS TO GO TO POLOKWANE. IT IS NOT MY FAULT THE PHONE IS NOT WORKING IT IS A MANUFACTURER PROBLEM WITH SAMSUNG. THE ISSUE IS BETWEEN SAMSUNG AND VODACOM. I AM PAYING A CONTRACT BUT DO NOT HAVE A PHONE WORKING. I AM REQUESTING A NEW HANDSET WHICH IS WORKING. IT IS UNACCEPTABLE TO SEND A PHONE AWAY FOR REPAIRS WHILE IT IS NOT MY FAULT. 20-11-2015 I AM UNABLE TO CONNECT TO LTE NETWORK OPERATOR, AND WAS ADVISED THAT NOW MAYBE THE INTERNAL ANTENNA IS DAMAGED. IT SEEMS AS THOUGH THE PHONE WAS NOT TESTED BEFORE IT LEFT THE REPAIR CENTER OR THAT NO PROPER FAULT FINDING WAS DONE. I NEED TO SEND MY PHONE IN FOR REPAIRS TO POLOKWANE AGAIN.
