WORST SERVICE EVER

I BOUGHT A SCREEN GUARD FOR MY SAMSUNG NOTE 4 (R250) FROM A CELL C AT MAPONYA MALL AND MY PHONE SCREEN WAS NOT CLEANED PROPERLY BEFORE THEY LAMINATED THE GUARD ON MY SCREEN , I HAVE GONE THERE TWICE AND THE SAME CONSULTANT KEEPS ON GIVING ME BAD ATTITUDE .TODAY HE SAID HE WILL TAKE OUT THE SCREEN GUARD AND SEND IT FOR TESTS I DID NOT OBLIGE AND I ASKED WHETHER THEY WILL COMPENSATE ME IF MY PHONE FALLS AND THE LCD SCREEN IS DAMAGED , HE LAUGHED AT ME AND SAID THEY WON'T .R250,00 IS A LOT OF MONEY TO SUPPORT A BUSINESS AND FOR SOME ONE TO GIVE YOU ATTITUDE.ALL I WANT IS MY R250.00 BACK AS CELL C HAS FAILED TO SOLVE MY SCREEN GUARD PROBLEM
