Complaint against shadesltd for non-delivery of order

I had placed an order from Shadesltd on 4th Aug worth Rs. 3399 and it was supposed to be delivered between 8 -10 days. I have been following up with them since quite some time for POD/ tracking number so that I could check the status on my own. I have been messaging and trying to call them through Instagram, my messages are being ready but they are not responding. This is a mental torture. I have spent my hard earned money, on the day of placing order, they immediately attended to my request but now, after getting the money, they have stopped responding. I don’t want the order now but would request for a refund, as I cannot take so much of unnecessary pressure. Please look into it.
