Onlineskyshop.com — Dispute with action camera bought

Address:

72, Pul Pehladpur, Delhi 110044

I had purchased an action camera from Onlineskyshop on 27 November 2020, the product which has been delivered is a fake copy of the actual product. I have tried to speak with the customer service several times but they are giving the refund. The product provided is cheap and is of no use and does not match as per the description provided on the site at all. They said the product is returnable in 30 days so I want to make a complaint and have legal action taken on them.
