Cell Phone being repaired for 4 weeks

I GAVE IN MY GALAXY NOTE 4 IN FOR REPAIRS FOUR WEEKS AGO AT MTN FLEURDAL. I CONTACTED A LADY NAME CELINE FOR SEVERAL TIMES NOW. SHE NEVER CAME BACK TO ME ON THE STATUS ON MY PHONE AND EVERY TIME SHE SAYS SHE WILL PHONE ME AND NEVER DID SHE PHONE ME. THIS MORNING I PHONE TWICE AND ONLY THE SECOND TIME SHE PHONED BACK AND TOLD ME THAT THEY ARE WAITING FOR A PART TO COME FROM OVERSEAS. THIS SERVICE IS PATHETIC INCLUDING THE CONSULTANT THAT I SPOKE TO. MY SPEAKER BROKE AND WHAT IS THE BIG DEAL TO REPLACE A SPEAKER. I AM WAITING YOU REPLY AND RESPONSE ON THIS MATTER EXACTLY WHAT YOU WILL DO IN REGARDS TO MY PHONE. I DO ALL MY BUSINESS FROM MY PHONE AND NOW EVERY NOW MY BISSINESS IS GOING DOWN DUE TO I NOT HAVING MY PHONE AND I ONLY COULD WORK FROM A COMPUTER WHICH I CAN'T ACCESS AS MUCH. I WOULD NEVER RECOMMEND ANYBODY EVER AGAIN TO MTN. I WASN'T A SOLUTION IMMEDIATELY.
