Bad service

My Samsung S5 fell and a slight crack appeared. Phone is 18 mths old. Took it to Summer-set West Mall Samsung shop. Asked the shop assistant about the free replacement screen for my phone. Explained that it was 18 mths old. He takes the phone, rip's off the plastic screen protector, crushes it and gives it back to me. Takes the phone to the manager who says its a hairline crack and does not need replacement. Including that my warranty has expired on the replacement screen. Secondly that they do not even have screen replacements for the S5. I then asked what about my screen protector. Offers me one to BUY, this after he ripped of a perfect good one at R290. I objected at the price and he says ok he will give it to me at R190. I walked out and bought one across the road for R80. What ******* client service. Breaking the plastic off because he could not se the hairline crack. Then offering me one for the exuberant price of R290 and discounting it by R100 when I walked out the staore. Will never visit Samsung again.
