Avoonik — order not delivered and payment not refunded

I have placed an order (71517) with this site on 31 oct it was supposed to be delivered in 8 to 10 business days. Now its 13 november and the order status is still processing state. Can you please let me know when will i receive this order. When i try to open this site it won't open at all and i can't check any information about the product. I have also mailed them regarding the same on avoonik. [protected]@gmail.com id but they aren't even replying. Please help regarding the same. I have also received a call from someone from avoonik but they are asking for debit card details and otp which is not safe. Please help
