Ajio — Non-acceptance of the returned product

I have received the product without the price tag but only a tag in which no price details were mentioned also it didn't contained the customer's original receipt. As the quality is very poor and doesn't fits me I wanted to return it but the delivery agent denied to take it saying the order has no price tag
What can I do in this case
Was it my fault ajio didn't checked if it had original price tag or not
