Adidas — refund for the return

Address:	Ghaziabad, Uttar Pradesh, 201010
Website:	shop.adidas.co.in

I bought some item online from adidas with a guarantee of return in 30 days. I return two items and received refund only for one item, and mailing them continuously after, but no action has been taken since now on my continuous mails.
I have not received the refund of a returned item with product code br0807 with order no:[protected] has not been received.
