vastra of south instagram page - complaint on Instagram page as i recieved totally different product

i ordered two sets of lehengas from vastra of south (instagram page) as before ordering i reconfirmed many times as the product they are sending is same as shown in the picture or not they said yes and after receiving i realized its completely different as duppata is very small and belt they promised to send is missing and the blouse as shown in the picture is different as it is having embroidery but i received plain blouse and lehenga size is very small i request them to take this product back and refund my money
