SAMSUNG abusing another consumer

I took my phone in for repairs (Screen went black) to the Samsung store in Menlyn. More than a week later I had to call to follow up as no one came back to me yet. Upon calling them they stated that a quote was emailed to me with the cost of repairs for over R1700? There was an internal crack on the lcd? Now my phone does not have any marks or scratches on it, has never been dropped nor has it been handled in any manor that this could have been my own doing! Samsung is really abusing their power in the industry as no customer is ever with the technician when they open your phone and you as a consumer just have to accept their word as true! ...not because they make bad phones or do not want to pay for repairs out of their own pocket! The customer must suffer no matter what! This is unacceptable SAMSUNG and this is what we have to go through for supporting you! This is abuse!
