Reliance Trends — Sales return not done

Sir, I have purchased 2 ashmitha kurthas and 2 leggins from reliance trends on today 29/11/2014 showroom from payyanur branch My card no:[protected]. Unfortunately one of the kurtha we got was size very small instead of small. We went back to the showroom at 7:15 pm to change the kurtha.. We just demand to replace it with same item but medium size.but the sales man denied our request mentioning that the kurtha is under promotional scheme and cant take return.. As a loyal customer of reliance trends we request you to help us to get it replaced with medium size.
