Puma — Poor product quality

Address:

Mumbai City, Maharashtra

I purchased running shoe worth Rs.5499 on 6/8/2014 from inorbit mall, vashi, navi mumbai. I hardly used the 3-4 times and recently I noticed that it got torned from front completely, I just have to ask what kind of material you people use, i really thought that you charge customers for quality product but got worst experience as i think puma only cheat people by charging much more than actual worth of the product.
so, either my shoe should be replaced or money should be returned back to me.
