Adidas — poor service

Address:

Kolkata, West Bengal, 700150

I had purchased a track pant from adidas showroom (Grand arcade, kolkata) on 1.4.17. Within 15 days we noticed that the pant is full of bubbling.
At that time we were out of station. After returning i went to the showroom and ask for a replacement (On 25.4.17). They recorded the complain and gave me a complaint form. They assured me that i"ll get a replacement within few days.
I didn't get any call and when i saw the complaint from, which the shop gave me, my contact number written by them in the form was wrong. I went to the shop that day and told my problem. But at that day their behavior was very unexpectedly bad. They told me to choose something from the product"on sale". As those products were not of my choice, i requested them to give me same product which i had purchased.
They told me it was not possible. I asked them if they could call me when they get the product i wanted. But till now i didn't get any call from them.

It was not expected from such an esteemed brand. It is high time for some action to be taken.

A photo of complaint form is attached for your reference.
