Price does not match poor quality

Can someone at Guess please explain how you can pay R1650 for a Black Guess Jeans at Edgars and then 10 and a half Months later it starts to tear from the crotch area? This is a disgrace. So much money for such poor quality. If I wear it twice a month its a lot. How do you justify your high prices if the quality does not match it? This is just poor. I'm done with Guess.
