Avoonik — complaining about online order

Address:	641012
Website:	avoonik.com

On 28th october 2018 i have ordered one saree from avoonik website https://avoonik.com/

I have paid the total amount of rs.399/- though my debit card. Also i got the order confirmation message from avoonik. My order confirmation number is 54843. Delivery supposed to happen with in 8 to 10 days. After 10 days i called to the customer care number., but there is no proper response, they asked me to order the product again. Then i enquired about my payment to refund. They are very concentrate in asking my 16 digit debit card number, which i refused to give. Instead i said that i will give my account number to transfer. But they are not ready to refund my amount. Plenty of calls made and email also sent. After that when i checked with avoonik website there are plenty of complaints with same scenario.
Kindly help me to get the refund from theirside
