Saravana Stores — regarding exchange

Address:

Saravana stores pursawalakam, Chennai, Tamil Nadu, 600112

I bought a kids turban for rs. 435 while getting i said size problem is there ill exchange, but these ppl didn't inform there was no exchange for this product, when i came to exchange they behaved in a very rude manner telling no exchange, on top of that when i asked for manager they told me to contact reception, one guy named siva came and told its our mistake not to inform u that there is no exchange but we cant exchange he said blindly and left, is this the way u treat a customer really pathetic behavior.
