I ordered for the above product through their ad on facebook on COD basis on 8th Jun'19, which showed a sleek product with specific features. The product received on 9th Jun'19 is very different from the one shown in the ad and ordered by me, both in looks and in it's functioning. It seems to be locally produced rough copy of the product which does not have all the features described in the advertisement. Not only that, the response on phone number shown on the invoice is that it is an incorrect number. This looks like a case of deceiving the consumer through false advertising. I can't find a way to request them for a refund since there is no website address also.

I need to return the product and seek a refund of Rs. 500.- paid for the same.
