Adidas — Asking back for the item after purchase

Address:

New Delhi, Delhi, 110001

I bought a adidas superstar (women) size 3 from adidas originals store cannought place delhi. after 2hours i got a call saying that the shoe is defected and superstar doesn't come in size 3. being a loyal customer of this brand i do know that it does come in this size. i had a huge arguement with the staff over this issue. i am really disappointed with the way they insisted me to return the shoe. also, while purchasing the shoe, i remember the salesmen discussing that the shoe has been booked by someone else. but over the phone they are not willing to accept the fact. if this is the level of service adidas gives than you have lost one very loyal customer.
