Street Style Store — Product not delivered even after "4 months"

Address:	New Delhi, Delhi, 110088

I had ordered 4 shoes and 3 dresses from sss on 16th of april 2016. After frequent follow ups, i received my shoes and 2 of my dresses by 2nd of july. But still, they have not delivered the final top. When inquired, they give a fake reason of wrong contact number given. But i have updated my phone number and address to them on each of such emails of them (More than thrice). Now, when i asked for status, they apologized that the dress i ordered was on high demand and due to that the order was delayed for "4 months".In their terms and conditions, if the item is not shipped and if i cancel the order, they are liable for full refund (A screenshot of the same attached with this). I had requested to cancel the order and initiate refund. They never listened. I request to the authority to help me with getting my dress as soon as possible and prevent this fraudulent and unethical people from cheating others again by taking necessary actions against them. (Fyi. My order numbers are: #779847, #713725, #681357, #658980, #638918, #638906).
(To add, my undelivered order falls under the order no: #681357 which is shown as delivered in the site. And a delivered top is shown as undelivered)
(And also, their customer service number is fake which is never picked up)
