American Tourister — asked for repairing charge while the bag comes under the 3 years of warranty

Hi, i purchased one 67 mm american tourister bag on december 2016 and got the 3 years of warranty. During handling the wheels and handle got damages within few months. I went to american tourister repairing center at vadapalani, chennai. I showed him the bags and warranty card and asked him for repairing. The main thing is that bag comes in under warranty even they are asking me to charge to change the wheels and broken handles. Kindly put your more attention and don't misguide the customer during purchase. Please maintain your dignity and as said by your sellers kindly follow them.
Thanks
