ShopClues.com — Non-refund of money collected

I had ordered mobile cell on 17/10/2013 with ShopClues.com per Order # 23637629 and paid Rs. 6598/-. As I found the mobile ordered was not suitable for me, as per their policy I asked for cancellation of the Order. However I was informed that I should refuse the delivery and on receipt of the product by the seller I will get the refund and gave me Ticket # 1540721. However now more than three months have passed and on one pretext or other they have not refunded my money. They firstly informed me that they have refunded my money on 29/11/2013 per Bank transaction #[protected] which in fact was tr. # of my payment to them as it can be seen that the tr. is preceded by date of tr. On pointing out the same they asked for statement of my account which I submitted on 18/12/2013. After receipt of the same they informed me that they have remitted my money. I waited for about ten days and then asked them to submit Bank tr. number of the remittance to which they replied that they had in fact not remitted the money and asked for details of my account to enable to remit money. I promptly submitted the same. But I have till now not received the money.
