Reliance Trends — wrong commitment for exchange

Address:

whitefield, 560066

Hi,
Yesterday i bought some apparels @ your Reliance trends showroom in Forum Neighbourhood Mall Whitefield. Before selecting a product i checked with store team is there a exchange for product since its a gift which am buying for my Daughter, we found the size is very small i checked with store team they denied to give exchange because it was brought on Employee sale, Before me Selecting the product i have asked the Employee even they said yes we can exchange, now its other way round, I Approached the store manager but he Refused, i have left the product at the same store because no point taking the product... its really worst experience...
