Reliance Trends — kids jacket not accepting for exchange

Address:

Hyderabad, Andhra Pradesh, 500072

Purchased a kids jocket at kukatpally store and there is a size issue i trayed to exchange the same but they asking extra 250/- for same price product exchange.
When i tried to exchange they or not accepting and very rough behaviour.

And not issued the coupons also.

Such a warest service

Now the garnament is not at all useful to me

When i ask the customer desk they people roundly answered that you need to know the turms and conditions
Dam is i need to go and search for tc or is they need to explain to customers
