Using gloves 3 times and they break.

I purchased a pair of gloves, and after using them 3 times in 3 weeks of owning them, the lether on the fingertips started coming off, after taking the back to exchange them, I was told that sorry u have used them and they can't take it back, what the @#$%%^. They only lasted 3 weeks, and 3 times of use.
