BAD WORKMAN SHIP AND DAMAGES

I SENT MY IMAC'S FOR SCREEN REPAIRS PAID OVER R10 000 FOR BOTH AND WHEN I RECEIVED BACK A WEEK LATER ONE OF THE SCREENS FELL OUT OF THE IMAC BECAUSE IT WAS NOT STUCK ON CORRECTLY AND AS A RESULT THE SCREEN CRACKED. I WAS FORCED TO PAY AGAIN FOR THE SCREEN. I THEN SENT THE SECOND ONE IN BECAUSE THE SCREEN WAS LOOSE AND LEARNT FROM THE FIRST ONE THAT THE WORKMANSHIP WAS BAD. THEY DID NOT TAKE ANY RESPONSABLITY FOR THIS AND I AM TAKING THIS FORWARD . PLEASE LEARN FROM THIS AND RATHER USE A APPLE CERTIFIED DEALER.
