Colorplus — Bad quality fabric used for trousers

I had purchased few readymade garments from Colour Plus shop at Inorbit mall in Vashi. The total value was more than 10K.
Today while in the train, while sitting on my EC class chair in Mumbai Ahmedabad Tejas Express, my trouser teared off from behind and I was put in very bad situation.
This is really a bad quality of fabric that could not sustain even a year. I have taken the picture of torn pant and thrown the pant in garbage.
