MY PHONE WAS DAMAGED

IN MARCH I TOOK MY FOR IN FOR REPAIRS TO ONE OF EDCON STORES (EDGARS WEST STREET), MY PHONE WAS BOOK IN FOR REPAIRS AND I WAS SUPPOSED TO BE NOTIFIED THAT MY WAS READY AFTER REPAIRS BUT THIS DID NOT HAPPEN I HAD TO FOLLOW UP MYSELF. I AFTER HAD MY PHONE BACK I NOTICED THAT THERE WERE COUPLE OF THINGS WRONG SO I TOOK IT BACK TO THERE STORE AND I WAS TOLD TO TAKE IT TO A VODACOM REPAIR SHOP AND WHEN I DID I HAD BOOK MY PHONE IN FOR A WEEK AGAIN TO BE CHECKED AND WHEN I COLLECTED MY PHONE I WAS TOLD THEY CANNOT FIX THE PROBLEMS MY PHONE HAS BECAUSE MY INSURANCE USED GENERIC PARTS. I PAY MY INSURANCE ON TIME EVERY MONTH I HAVE NEVER BEEN ON ARREARS WITH MY ACCOUNT AND FOR ONCE I WANT THE INSURANCE TO FIX MY PHONE BUT THEY USED CHEAP PARTS TO FIX IT AND CAUSE MORE PROBLEMS ON MY PHONE, NOW I HAVE BEEN TOLD TO TAKE IT BACK AGAIN!!! I AM NOT HAPPY AT ALL AND I DON'T BELIEVE I GO VALUE FOR MY MONEY.
