not received my refund of my product

I bought this wireless subwoofer from snapdeal at 21 aug 2015.the product had 1 year warranty, on 22 april 2016 it stopped working because of some minor fault, so i called snapdeal for product repair they refused to send me a home repair service and told me to send my whole product along with invoice and warranty card, i sent as discussed they tod me to refund my courier charges .snapdeal team told me the refund will be placed instead of repair or replacement because the product is now costlier than previous date i bought the product on .so i accepted the request and gave snapdeal team my account number to refund me.the actual refund of the product wasinitiated on 12 may 2016 but no amount is being transphered to my account till now as on 03-06-2016.my complaint number for the product is”22212635″
i called too many times at snapdeal helpline but they just refuse to refund and every time give excuses of complaint being processed .
