Samsonite India — Black Label Veron II Backpack (Regular)

Hello,
I purchased the product mentioned above (Offline) saying this is for my girlfriend and I will need to return if she does not like it. I then tried to return it in store, in original condition within a week (From where i bought it) and they refused to take it back. On the Terms and conditions online it says a product can be returned if the customer is unhappy. Paying such high prices for a backpack and getting such terrible services, Some replies on emails even taking a couple of days, some replies after 3-4 emails. Terrible service, I do not need any product from a company where the staff is not professional. I do not trust a brand like this and would like a full refund. I still have the product unused and in Original state.
Thank you.
