Limeline.in - Wrong order delivered

I had placed an order for * dresses on limeline.in on May *, ****, and made a card payment of Rs ****/-. They confirmed the same vide order no. *****. They said they have dispatched my order but when I received the courier I found that the bill copy mentioned only one dress no.*** and after opening the parcel it was found that it is a saree which I had not ordered and cost of it was Rs ***/-.
I once again called the courier guy and he said their work is to just deliver goods. Immediately I called the number of the supplier. The answer was they will call back. But to date, no one called. Then put the message on their messenger but after one day they blocked me. Then I put the message on their online facebook ad but still no response. I don't know why they are not responding and who is at fault their despatch team or courier company. I also filled the return and refund form still no response. Also on the receipt limeline.in is not mentioned. However, it is my loss but I am shocked and surprised by their lack of response.
Now I am scared to do any online shopping.
What we some we reap. Mine is though small loss but the loss is a loss. I am honest and God will compensate even my small loss.
