Query: wore out in 6 weeks

I cannot believe this mat is falling apart. I purchased it 6 weeks ago. It is now crumbling where my feet typically go. I am so disappointed. I never purchased a "nice" yoga mat before and I was so excited when this arrived. It was nice and sticky and cushion-y. But this is way too expensive of a mat to be falling apart less than 2 months after arriving. Very, very dissatisfied.
