I BOUGHT A PHONE IN MAY 2015 SINCE THEN I HAVE HAD NOTHING BUT TROUBLE WITH THE PHONE. .IT IS A SAMSUNG GRAND NOE WHEN A CALL COMES IN IT SOUND AS IF THE PERSON IS TALKING UNDERWATER. THE FIRST TIME I TOOK IT TO VODACOM THEY SAID THERE WAS NOTHING WRONG WITH IT THAT WAS IN THE SAME WEEK I BOUGHT THE PHONE..ON VODACOMS ADVISE WE TOOK THE PHONE TO THE SMART CARE CENTRE NEAR NI CITY ALL THEY SAID WAS BOOK IT IN AND THAT THE MOST FIGHTS THEY HAVE EVERYDAY WAS WITH CLIENTS WHO NEED THEIR PHONES . I USE MY PHONE FOR WORK PURPOSES.THEREAFTER WE TOOK THE PHONE BACK TO VODACOM WHO SENT IN IN TO THEIR REPAIR CENTRE .THE REPORT CAME BACK THAT MECHANICAL PARTS HAD BEEN REPLACED. HOWEVER THE DATA WAS UP-DATE AND NO PARTS REPLACE. LO AND BEHOLD THE PHONE WAS THE SAME IT WAS RESENT IN.WITH THE REPORT THAT THERE WAS A MISS ALIGNMENT WHEN CALLS COME IN. THE PHONE HAS BEEN GONE NOW FOR 4 WEEKS ALMOST TO DAY
