ShopClues.com — Money credited after saying no when it's delivered

I orderd a redmi note 4g from shopclues.com
By my credit card and day after tomorrow i decided not to buy this product.
For cancellation of this product i called their customer care centre and they said that " no issue sir when delivery will come to your place just simply say that i dont want it now and we will refund your deducted amount!
As they said i did exactly!
But now they are not refunding my money even they deducted 2extra installments!
Now i will not prefer or shop anytime in my whole life from shopclues
