Beyondpinkshop.com — I have not received my order even after 1.5 months of placing the order

I had placed an order with three dresses from this website with and I prepaid for the order. The date of order was - 10/6/2018. I have still not received the order. I have tried calling them so many times, but in all in vain. They answer the call and tell me that they will call back in 10 minutes and never call back.
I have been writing mails to them almost every alternate day to check upon the same, but they hardly bother to answer the mails also.
The customer harassment is at the peak with them, they themselves don't know about their shipments and order status.

I want my money back.
