Jeans hardly lasted 3 months

Hey<br> I bought a pair of very expensive guess jeans in March of this year. The idea of going way past my budget (over R1000) was to have a nice pair of jeans that will last me long enough and which I could use for special occasions.<br> I have had the jeans for 3 months now and it ripped in the front by the zip without any heavy/out of the ordinary activity done! This is incredibly upsetting to me as I paid a hell of a lot of money for the jeans which basically lasted 3 months now. I do not have the slip anymore as I really did not expect this to happen, but I can prove on my bank statements when and where I bought is (Guess in Canal Walk). <br> I am very upset as this is supposed to be a brand selling proper clothing that will at least last some time!!!!! I swear clothing from PEP lasts longer than this!
