Elanic — payment made but there is no record of it

Address:	Howrah, West Bengal, 711101
Website:	elanic

I had purchased products from elanic and opted for Cod for 2 orders worth Rs.350 and 400 respectively on 11/07/2018, but it showed that cod is not applicable for my pincode so I paid online, I got confirmation from my bank and razorpay(gateway for payments)but there is no record in elanic.These people are thief.They say that refund is already done everytime I ask for refund.Kindly look into the matter as there is no way out of it.
